"They're gone mad. That psychopath has gone completely mad!" Heng pushed open the door of the special investigation team's room with one elbow and made the door vibrate almost off its hinges. He threw a bundle of thick files he was carrying onto his desk, took off the lanyard containing his ID card and hit the crime board hard.

Freen stepped behind him with a much different expression—she was calmer and controlled herself better than Heng. She entered casually and didn't forget to close the door behind her without making any sound. Taking a position in front of Heng's desk, she grabbed a bundle of files and brought them to her desk to be unpacked and tidied up.

Mind—as an honored guest who got a golden ticket to enter the room of the special investigation team, certainly did not expect that the welcome she got after driving through the traffic jams of Bangkok was the screams and bangs of a frustrated young man and the slamming of piles of papers that were immediately given to her.

Heng himself had hardly ever screamed like that before—except when he was yelling at a suspect who was trying to run away from him—so anything that made the man scream like a that must not be something good. Putting down the papers containing the autopsy report and pausing the CCTV camera footage she was analyzing, Noey got up and walked slowly towards Freen.

Freen glanced sideways for a few seconds as she heard the sound of footsteps approaching her. So to appreciate that person, Freen lifted her face and put on a faint smile. "Need my help, Noey?" she asked. She slipped a finger across the page of the file to avoid losing track of what she had last read.

Glanced at Heng who was standing stiffly in front of the crime board while accompanied by Irin—it seemed the two of them were having a discussion. Occasionally Irin tapped the board with her fingertips while Heng still kept his hands on his hips—Noey whispered right near Freen's ear. "Why is our team lead like that? I'm worried he'll go crazy like Becky."

"If I hear you call Rebecca crazy one more time, I'll make sure your ugly teeth fall out," Freen grinned widely and the smile that made Noey uncomfortable was still there when Freen looked down again to read the document that made Heng go crazy. Just now.

Noey exhaled, slightly irritated by Freen's words that seemed to challenge her to a fight. Well, it doesn't matter. After all, she is also quite skilled in martial arts. But if you look closely, Freen doesn't seem like someone who can go down with just five blows to the head. The woman looked stronger than she looked and Noey finally decided to stay silent to avoid bruises all over her body—or worse, she could come to the office with broken arm and fingers.

"Okay, I'm sorry. Sheesh, since when were you so overprotective of her, huh? You've only known each other for about a month." Noey finally answered, although a split second later she cursed herself and wanted to slap her mouth. Damn it. I shouldn't have brought up Becky's name any further in front of her. Fuck me.

Freen paused for a moment and looked at Noey with one raised eyebrow, as if to ask what-is-your-business-of-that-kind of thing-of me?

The taller woman then sighed and decided to ignore what Noey had just said. She took one of the sheets of paper from the file bundle she was carrying, then handed it to Noey. "Becca was terrorized by the killer again after she temporarily moved out of her house. This time, the killer left a severed hand on top of her car and when identified... we got new DNA." she explained.

Noey groaned while rubbing her face rather roughly. She's really exhausted and tired now. Months of struggling with corpses and very slippery assassins like this managed to erode her sanity little by little. In fact, through the evidence and witness statements they previously obtained, they should have obtained something sufficient to arrest the perpetrator. But now, there is another new corpse that was just discovered after pieces of her body were placed in Becca's car to terrorize her.

"Ah... okay," Noey mumbled. She received the paper Freen gave her and skimmed through it. At first she was still normal because nothing attracted her. But when she came to the end of the report, to be precise at the information that showed detailed identification results, her mouth dropped open.

"See?" the woman who had a higher rank than her then smiled, implicitly mocking Noey for her exaggerated response. "I think we can catch that psycho if we move faster without resting 24/7, with the condition that once we catch her, we will die from too much fatigue." she muttered.

The short-haired sergeant like the man next to her then snorted, "Better to die than to be faced with a psychos like this every day."

"Hey, watch your mouth," said the Lieutenant. Freen then completely put down the report papers—she also already knew what they contained—and gestured for Noey to join Heng, Irin, and Mind. When she was close enough, Freen immediately put her left hand in her trouser pocket as she glared at Heng.

The man still looked frustrated, just like before. Looks like the contents of the report earlier still affect him a lot. The discovery of his fingerprints on the car used by the perpetrator seemed to make him feel cornered and cornered. He guessed, how many people already know? How many people have read it? Also, who has the original documents of the forensic report that she deleted from Nam's office?

"It won't be this big if you immediately surrender with open arms, Asavarid." Freen started. "You must come with us to be examined, sergeant."

"Argh!" suddenly, Heng shouted. Again, he hit the crime board harder and made several pieces of the attached photos fall on the floor. Without bothering to look down and pick up the fallen photos and notes, Heng stepped forward and raised his index finger in front of Freen's eyes. "You! You must have set me up, asshole. Who said I went to Nam's office to delete the document? I went there just to check and take the remaining evidence!"

"Deleting documents?" Freen was flabbergasted. Somewhat surprised because Heng suddenly brought up the topic of the document that had been deleted. Even though Freen still hasn't talked about it. "You just saw the document in hard copy a few minutes ago. Why are you talking now about the document you deleted?"

Heng gasped. She seemed to have trouble answering and that made Freen press her even further, "You're caught red-handed, bastard. Why did you delete the document? Want to hide your involvement in this case? Is that why you deliberately framed Doctor Nam?"

"Freen, you misunderstood! You don't understand. I swear that I never touched that car! You know I did not come to the location! What I did was just to protect my career! If I get in trouble because of that, who will take care of this case? Becky can't be relied on anymore!" Heng pushed Freen's body away with a single thump of his hand. However, Freen didn't fall and was still able to stand on her two feet without taking a single step back. "And if you're talking about Doctor Nam being framed, look at me! I'm being framed too! How could my fingerprints be there while I was at home!"

When Becca's name came out of Heng's mouth, Freen, who was originally trying to hold back her emotions, exploded at that instant. She clenched her fists, then punched and pushed Heng's chest back. "Hey, if you say anything bad about Becca again. I'm going to—" She pulled Heng's shirt and intended to use her forehead to smack the man's nose.

DRRRT DRRRT DRRRT

The vibration of the cell phone that she placed on the table made Freen release her grip. Heng was lucky and owed a debt of gratitude to whoever contacted Freen at that time, because if they didn't, they might have gotten into a bloody, furious fight.

Saint? The young Chankimha raised an eyebrow. Why did he contact me?

"Hello Saint. Is there something you need?"

"It seems so. Listen, Lieutenant. I'm calling to give you the news that your entire team has been called by the Ethics Council for review. Seng had just confessed that the person who ordered him to experiment on Becky is a police officer at the Bangkok regional office. This is urgent, if you don't come... I'm afraid the special investigation team will be forcibly disbanded."

Freen exhaled harshly. Without realizing it, her grip on the phone tightened. She did not put the phone down from her ear even though the call had been unilaterally cut off by Saint as she turned and faced her teammate's face and said, "Saint called us all to the examination room. If we refuse to come, the special investigation team will be disbanded and this case will be transferred to another team."

There was silence when Freen finished her sentence coldly. Even though they were getting used to her somewhat sinister character, this time her words managed to make them feel frantic half to death. An examination room may be compared to a courtroom, with high-ranking regional office officials acting as judges and police personnel being investigated as defendants.

Anyone who goes in there to be questioned may have violated the police code of ethics, injured integrity, or even committed a serious violation that has the potential to damage the good name of the police. With the entire special investigation team summoned, that means they've done one of the three (or maybe all of them, who knows?)

So, with sour faces and reddened with anger and anxiety, the four personnel immediately stepped out of the investigation team room quickly. Before leaving, Freen left the items in the room with Mind and at the same time conveyed the message that no one is allowed to enter except team members. Mind nodded in understanding and let her friend go after her other co-workers.

Apparently, a re-examination was carried out on Seng—who was detained for having attempted to murder Becca—without the knowledge of the members of the investigative team. Through this investigation, it was revealed that the person who ordered Becca to surrender was a fellow police officer who was working on a murder case. When questioned further, Seng could only provide limited information; the perpetrator of the murder probably came from within the police institution.

The first step they took was to examine every member of the investigation team—Becca was removed from the list because she was deemed not in good psychological condition so she was not suspected. Saint and several higher ranking and more experienced police inspectors were waiting for each member of the team in a closed room. They will be called one by one for detailed information as possible to determine whether they are potential suspects or free from suspicion.

Irin was the first to be called into the room. Nothing could be suspected of her because she answered all questions well and was able to provide a plausible alibi. While on the team, her duties were mostly concerned with field inspections and documenting crime scenes. Rarely does she directly intervene in matters relating to investigative reports and securing evidence.

In addition, regarding the terror that was perpetrated on Becca, they could find no reason why Irin could do such a heinous thing. While working together for about three years, Irin admitted that she had only met Becca's family less than five times. The relationship between the two was only limited to work colleagues and nothing suspicious was found about this woman so she was given permission to leave the room after being examined for 15 minutes.

The second person called in was Noey. Just like Irin, except that she had only known Becca for a year—two years of her early career in the police she spent in the Narcotics Division. The woman looked panicked and kept reassuring herself that she was not involved in the murder case nor did she know anything about Seng. While serving on the investigation team, she took care of a lot of things related to administration and IT such as recovering lost data from device memory, forcibly unlocking encrypted cellphones or laptops, tracking and finding someone's precise location via cellphone networks and so on.

Subsequently, Heng had the opportunity to step in and defend himself in front of the inspectors. Since his fingerprints were found on the car the perpetrator used to kill Ring, for now, all suspicion is on him. He finally admitted that he came to Forensic Doctor Nam's office for the second time not to retrieve the evidence left behind, but to delete the identification report document from the doctor's office computer.

From further investigation, they met two days before Nam was arrested because a box full of bottles of bleach was found in her office. At that time, Heng came with the aim of examining the autopsy of the corpse and confirming the identification report of fingerprints and DNA from the camera and bugging device left by the suspect at Becca's house. It was then that he knew that his fingerprints had been found at the crime scene, even though he was not at all present at the location when the police investigated the crime scene because he was at her house to sort out his family's problems.

Heng knew full well that his position was not good and his career could be ruined if someone else discovered the fact that his fingerprints were found in the wrong place, in contrast to Freen who was indeed at the location so it made sense that her fingerprints were left behind. So without a second thought, he deleted the document when he had the chance. Although the attempt failed because apparently someone had checked the document beforehand and kept a copy.

When asked if he was the one who deliberately left the box containing the bloody bottles, Heng quickly shook his head and admitted that he didn't know about the box until Freen found it.

The last person to enter the room was Freen. She answered all questions with everything she knew and nothing was covered up. She also explained that the reason her fingerprints were found in the car was because she was careless. She is a new personnel, so she is not asked too many questions. So don't be surprised why Freen was able to come out after five minutes of being held in the room.

With the completion of the inspection of the four people, then all is done. Exactly one hour later, Saint gave the news that Heng was sanctioned in the form of a demotion and was in the surveillance phase for manipulating important evidence that could interfere with the investigation. Moreover, the evidence is related to an important case that is attracting public attention so that his actions are considered as an attempt to obstruct the investigation process.

They gathered again in their team's special room after receiving orders. As soon as they opened the door, they were greeted by a crime board that was flipped over and showed the other side. Now that part of the board is full of writings inscribed by Mind using a marker that she took from Freen's desk.

"Forgive my impudence, but I read all of your notes and linked them to the investigation report. Maybe a little confusing, but I managed to arrange everything like this," said Mind. She walked over to Freen and tapped the marker on her shoulder. "I don't know what happened to all of you out there, but this case still needs to be handled."

Freen glanced at Heng, and the man suddenly looked away and walked past her to pick up the car keys lying on the work table, then he took a quick step out of the room with a loud bang on the door as he closed it. He really couldn't be worked with. No wonder he never got promoted, she thought.

A soft touch landed on her shoulder. When she looked to the side, Irin was already standing beside her and lowered her hand. "Don't mind him. You'll see, Heng will be back in a few hours... or maybe two days."

"I don't care if he comes or stays away from this place, that has nothing to do with me." Freen chuckled "That fucking sergeant better not come with the same face as just now. Because I wouldn't think twice about slapping his face against the asphalt..." the woman paused for a few seconds and noticing the silence caused by her words and the horrified looks Noey and Irin were looking at her, Freen hastily interjected, "Just kidding."

Mind may be used to Freen's sadistic side, but it might be a little different from Noey and Irin. Since childhood, Freen has been like that. And she grew up without being with the strange side of herself that Mind often calls a psycho even though Freen herself strongly denies that she is not and does not want to be called that. Later they will get used to it, Mind thought to herself.

Freen walked over to the board and folded her arms across her chest. Her eyes looked straight at the arrangement of writing on the board with focus, while her mind was trying hard to arrange all the clues she found into one.

"After finding out that Heng's fingerprints were left at the crime scene and the car was a rental car, I immediately came to the place where the car was rented out. I vividly remember the landlord saying that the car was rented for one month with cash payments, and the person who came to rent was a woman in a black hat with long hair in a ponytail," Freen's index finger touched a blank part of the board and dragged it along a few centimeters. "When I showed the photos obtained from the CCTV camera footage at Becca's house and mentioned the characteristics we got from eyewitnesses, the owner of the car rental confirmed everything."

"Sly fox. She knew we would have a hard time tracking her through transaction history because she was using cash." Noey mumbled. A second later she turned to Irin. "Hey, didn't that person also say something similar?"

"You are right. The person who was arrested by the Traffic Security Division for assaulting Becca said the same thing. He claimed to have met directly with the person who gave him the order. He said the person was actually a woman with long hair and sharp eyes," Irin replied. She walked back to her desk to grab her cell phone to play the tape of the interrogation she conducted a few hours ago. The cell phone was placed on the table, its moderately loud sound allowed to echo through the room while everyone present listened intently. "His testimony matches to Becky's neighbor who came in at the time."

Freen muttered. "What about the hammer found in the car? Is there anything to be found there?"

"Unfortunately, nothing. The perpetrator didn't even use the hammer to hit the victim's head because no defects were found in the iron during a thorough inspection." Erin answered.

"She took the hammer used to kill the victim and left another hammer of the exact same shape and size in the car to trick us, again. No wonder the hammer was drowned in blood. She wants us to linger over the hammer while she wanders out there with human remains." The young lieutenant tried to conclude. She stepped back, putting some distance between herself and the board. She felt like she would vomit if she had to stare at her for 5 minutes longer. "I feel something's off. Why are all these events happening sequentially. That is, why every time we take one step forward to get something new, there is always something else that prevents us from getting it. Doctor Nam is framed, Rebecca is temporarily suspended from her post for psychiatric reasons,

"Just like Seng said. The psychopath comes from among the police. She was used to thinking tactically and planning neatly like this. From now on, we have to be careful," this time Mind joined the conversation. Her gaze turned serious. "I've been studying the pattern she made so far. And I can conclude that she actually only targets one person. You all know who. In other words, the people she's killing now are just a countdown."

"In that case, then, Irin, can you come to the car rental at that time? Ask them for ID cards or any items that psycho uses as collateral for renting a car. Just leave Doctor Nam's business and the piece of human hand I found in Becca's car." Freen turned her face towards Irin. The woman she called her name immediately nodded without asking anything and went out of the room with her car keys and jacket.

Stupidly, Irin left her handy talky on the table so Noey needed to follow her out. Right now, there was only Mind and Freen in the room. Each of them seemed busy struggling with notes and assumptions. For several minutes, the 20-degree room was filled with silence. None of them spoke. Only the hum of the air conditioner and the ticking of the clock were the only sources of sound.

Until finally the sound of tapping shoes was heard and made Freen almost drop the paper she was reading.

"There is a possibility that that psycho is standing between us right now." Mind placed the marker that she had been holding on to Freen's desk before continuing her sentence in a lower voice, "Or she is somewhere watching us from afar like chess pieces."

Hearing that, Freen then frowned. She replied, "What makes you so sure?"

"Who knows. Your eyes tells."

"Well," Freen laughed sadly. "Say, do you think I've become a good person?"

***

The sound of the metal door creaking from the special detention room was in made him reflexively open his eyes and stare straight into the dark gap in the door. The moonlight filtered through the ventilation openings so he could see who had come inside to meet him. It made his heart beat fast because everyone who entered almost always came not to let him out, but to beat him or drag him into the interrogation room only to be tortured.

God, that traumatized him so much. While waiting for his examination to be completed, he was forced to live in a narrow room separate from the other detention rooms. More precisely, he was in an isolation room. As a police officer, of course being a prisoner and being placed in isolation like this is an insult to self-esteem.

But what can he do? All of this is indeed the fruit of his very stupid actions. If only... if he had made him brain work and think rationally before accepting the offer from that crazy psychopath... maybe it wouldn't have ended like this. If only he wasn't tempted by getting money instantly to pay for the treatment of his mother who was lying in the hospital because of cancer, he probably wouldn't be stuck here with all the accusations and criminal threats aimed at him.

"I'm surprised someone like you did your job well. But too bad, you can't keep your mouth shut like you promised me. It seems you have forgotten who you are working with."

Seng cleared his throat, "You promised to let me go after I attacked Becky. You're the one who didn't carry out our agreement, you bastard!"

"You misunderstood. I will indeed let you go, but on condition that you keep everything you say," the killer answered lightly. "But why did you say something unnecessary like that?"

A polaroid photo dropped right in front of Seng. Every time that polaroid photo appeared, there was bound to be something bad behind it—Seng knew that so well that he immediately grabbed the cursed photo and held it up to let the moonlight shine on it. His eyes immediately heated up, and in that second the man immediately jerked backwards along with the polaroid photos that he threw forward.

He didn't expect that something like this would happen to his family. He still couldn't believe that the mutilated body as shown in the photo was really him own mother and father. He thought he was too tired, too crazy to the point that he assumed the owner of the severed head was a member of his family.

But when he glanced out of breath at the photo, he realized that he wasn't hallucinating. The pieces of the body really belonged to his parents—they were dismembered to resemble blood-red mannequins being disassembled.

"I killed them and keep them somewhere to rot. Yesterday I took her hand and put it on top of Rebecca Armstrong's car. You should know how she responded when she found her; she was as terrified as fuck." The killer then laughed softly as she took out a gun from under her belt buckle. She showed the gun to Seng, then peeked at the bullets. "This is your gun. You know why I took them from the evidence depository. What a shame, I thought we could work together a bit longer but... it seems like I need to cut off all the connections we have, right now."

Seng growled. He pushed forward, about to beat up the person in front of him. But alas, the metal cuff links on both wrists restrained most of his movement. The man ended up hitting his head against the wall behind him, crying, but also groaning with emotion. "Crazy... you're crazy! Damn it, I should have never believed you. I should have killed you when I had the chance! Argh!"

"It should be. But that's not what an obedient dog like you should do," the killer replied, "just so you know, after you promised to cooperate with me and broke the promise we made, the only way to get you off of me is to give your life to me. Now, be a good dog and bow your head for me."

"I won't make the same mistake twice!" he shouted. The sound of the metal handcuffs clattering was deafening as Seng tried so hard to break it and free it by banging it hard against the wall. It hardly changed anything other than his hand which started to swell and bleed. "This time I will kill you. I will really kill you. You fucking bastard, you will dead by my hands!"

Hearing the despairing voice of this helpless man in front of her, the killer laughed heartily as if she was watching a comedy show with comedians who were the best at throwing bad jokes. Here, Seng is the stupidest comedian she has ever met. That bullshit really amused her. He will kill her? It was the most preposterous remark he had ever heard from someone.

How could someone who had killed dozens of people like her could be killed so easily? She had seen something worse before, so, the hell with all the people trying to chase down and kill her—she would have killed them before their fingertips even touched her skin.

"Just do it," she finally answered, bringing his head closer so that they were only inches apart. At that close distance, Seng could see the killer's face very, very clearly. The police ID card worn by the killer using a lanyard was also clearly visible before his eyes.

Without thinking, he pulled the lanyard as hard as he could. Seng intended to strangle her by tying the lanyard tighter around her neck. With one swift movement, Seng lunged forward and passed the killer's body. Thus, the lanyard's binding managed to make the killer fall backwards and make her lanyard broken so that it was thrown against the back of the steel door.

When Seng tried to stand up and immediately threw a punch at the killer. Seeing that, she immediately rolled to the side and let Seng's fist hit the cement floor very hard. He groaned in pain, uttered swear words and other harsh language. His knuckles felt crushed and cracked, making him unable to move the fingers of his right hand.

Taking this opportunity, the killer suddenly stood up and threw Seng's head against the wall. It didn't stop there, she also stepped on Seng's neck and dragged his body, forcing the man to sit down with his limp body. A click sound is heard, a sign that someone has released the safety of the gun and is ready to fire the bullet.

Seng couldn't move anymore when he was forced to grip the pistol grip and his index finger was led to touch the trigger of the gun. He could already guess what would happen to him after this, and with his body already limp and half dead, he wouldn't be able to fight anymore.

"Thank you for your cooperation so far, Wichai Saefant." after she said those words, her grip on Seng's hand which she forced to grip the gun became tighter. She then picked him up and put the gun into Seng's mouth, who could only cry, scream and thrash about.

Seng tried to push the person in front of him. Several times he even tried to use his injured leg to kick her so he could give them enough distance to fight back. "No, no! Don't! I beg you, don't kill me! I will—urgh!" his sentence was cut short when the point of the gun was further inserted into his mouth, while his neck was being strangled very tightly.

The stranglehold made his body go limp and it was hard to breathe. It was so strong that it reduced the supply of oxygen to his brain drastically and made his vision start to fill with black dots. His grip gradually loosened as his body gradually weakened. Seng roared loudly, trying to expel what was left of his strength in the form of a scream.

However, unfortunately, nothing can save him from the angel of death who has come to pick him up now. Even if he screamed as loud as he could until him vocal cords were severed, the sound of his screams would still not be heard from outside. He stared straight at the figure of the killer grinning broadly in front of him. That face... still clearly visible even though his eyes were filled with spilled tears.

Her sharp eyes, a wide smile showing white teeth that made him shiver and scared to death, and the scars on her face.

And that was the last thing he saw before the gun that was in his mouth fired and made him entire head scatter all over the place.
