A/n: just because this is a more chill story doesn't mean there won't be a little bit of drama ;)

How do sirens express their love? Many ways. But one way was creating a custom lure song for their lover.

And so you leaned up against L's boat docked at the shoreline and and with a scroll of parchment in your lap you pondered on lyrics for this song of yours.

The lament of Lawliet.

He loved your singing of the lament of Orpheus so much, you figured you'd take some inspiration and write him his own lament. And I when you sing it at the correct tone and tune and the music fills the air and he hears it, it'll draw him right to you. No matter how far away, he'll hear it and find you. That way if you're ever separated, all you have to do is lure him back in.

The pencil scratches the parchment as you hum the tune, making sure all the words fit and sounds just as you wanted them to. The only other sounds around you being the rustling of leaves in the wind and occasional water bird diving for fish.

For him, you'd write your heart out. For him, you'd tell the story of your love through song.

Land above, hear my plea
To see my love beside me.
Land below, under the sea
His anchor weighs upon me.
Fasten my shell upon his glee 
So he may stay connected to me.

My human boy.

Close enough, his heart I can see
No doubts to betray the better of me.
A single kiss is all it would be
That beautiful smile shall stick with me.

Ever on.

Calm rivers
Winds a lee
But now the suns upon us
He's forced to leave
Without me.

Until next time
until next time
until next time
until next time, Lawliet.

Perfect. The day you'd spend by his boat brain storming lyrics and making sure they fit the tune had paid off. And now you'd written a lure call, just for L. Hopefully he liked it, hopefully it worked. Next time he came to visit you'd have to sing it for him.

Satisfied with your work, you rolled up the scroll and placed it in the boat for when he came back. You often hung around the area even when he wasn't here, just because you liked knowing it was where he dwelled on his visits. Stretching out your arms and getting off the side of the boat you landed back in the water with a splash and shook the hair from your eyes when you surfaced.

Floating on your back and looking up at the clouds you couldn't help but wait in anticipation for him to return. Even though you knew he couldn't come down here in the middle of the day, you still found yourself waiting for his arrival. You needed to pass the time, keep your mind off him for two seconds.

Ducking under the water, you figured you'd head out to sea for the rest of the day. Maybe you can keep yourself occupied there, watch the reef life or something. Swimming up the river, passing some other water creatures on the way you made your way out to sea. The fresh water became salty, and the blue tinge of the ocean filled the surroundings.

Although your efforts to distract yourself seemed futile. Thoughts kept popping into your mind as you swum, all coming back to L.

'I should show him this reef'
'I haven't taken him for an ocean swim yet'
'Maybe I should get him a wetsuit to stay warm in the colder waters?'
'What's his favourite fish?'
'Has he swum with dolphins?'

It was impossible to keep him from your mind. Ever since that kiss...

He was just as sweet at the sugary treats he adored. His nerves were cute, and his awe was adorable. His first kiss was stolen by a siren and that siren was you, what an honour to have kissed the worlds greatest detective.

Even if this love you shared had to stay hidden, you'd hold out for him. Wait for him to return every other night. For you craved more sweet kisses like that first one...

Just as you thought you couldn't stop thinking about him, something happened to catch your attention down at the sea bed.

A ship wreck. You hadn't seen this one before, must be recent. But usually the ocean dwellers help those who own the vessel collect it's treasures and return them. This one seemed to be untouched. The name on the front of the boat read 'the skimmer'.

You swum down, heading toward it and you circled the perimeter looking for the cause of the sinking. It seemed to be a hole in the hull, you weren't sure what caused it but it looked jagged and unplanned. Swimming through the hole into the ship, you found that the inside hasn't even has sea life like weed or barnacles on it yet. So clearly this was very recent. Deciding to check the cabin, you circled back around the the deck of the ship and found the door.

It was jammed, and the water pressure didn't help. But after whacking it with your tail a few times, you managed to make a dent and with that dent you pushed as hard as you could to break the lock off his hinges. There was a loud clang, and the door finally opened.

The inside was furnished, it looked to be someone's personal vessel. There was still furniture floating in the water and smaller belongings like clothes and plates scattered about. Carefully swimming inside, you looked around it was almost as if someone took a normal room of a house and put it underwater.

There was an area to drive the boat, and an area to lounge in, another door down the back and a trapdoor on the floor. You pulled the trapdoor open to investigate and found all the usual safety supplied in there. Inflatable life raft, life vests, rations, oars and first aid.

Weird... if the boat was taking on water wouldn't have the crew taken the life raft to abandon ship with? Or at least taken a life vest?

You turned to the other door, and swam toward it. To your surprise, this one wasn't just jammed from the water pressure. It was locked. Judging from the type of boat this was, this was likely a small bedroom and bathroom area.

You couldn't find a way to make the lock undo itself, so again you decided to try and dent the door so you could push it off the hinges. Your tail was long, and very strong so if you could get the first door open surly you could get this one too.

You kicked it with your tail, once, twice, three times until finally you made a dent. One more and you could push it off its hinges.

The loud sound of your tail hitting the metal door echoed through the water, and you could finally push the door. You squeezed your body between the gap in the frame and the door in the dent and with all your might, pushed it so hard the rust on the hinges gave way and they snapped right in half. The door sunk the to the floor of the ship and as you thought, the room was a bedroom area.

And again, everything looked like it was left completely in place. Like no one had even tried to abandon ship. There was a curtain that separated the bed from the rest of the room, so after looking done and seeing nothing too interesting, you figured you'd check behind the curtain.

And the second you did, you wished you didn't.

The sight you saw behind that curtain made you scream a hissing like sound sirens made when in distress bubbles escaping your mouth as you jumped back at the sight.

Freshly decomposing bodies.

Two of them, lying in bed floating half decomposed in the water. Partial skeleton, partial rotting flesh.

You felt like throwing up, and immediately turned on your fins and swam right out of the cabin and back up to the surface.

"What the fuck- holy shit-" you panicked.

You froze for a moment processing what you just saw.

And in that moment it hit you.

Two dead bodies in a locked room, no safety equipment touched, no signs of struggle, and a jagged hole in the hull.

This was a murder.

You'd just found a crime scene, the watery grave of two victims.

In a complete panic, your first thought was to get to the seaside down and call the coast guard to get the police to retrieve the wreck. You'd never swum so hard in your life, unable to get the image of the rotting corpses out of your head. You felt sick.

The coast guard often patrolled the docks of the seaside town, and it didn't take long at all for you told find a boat anchored just off the shore probably watching for any dangerous sharks. Grabbing the side of the boat and pulling yourself up, you took a second to catch your breath as the two guards on duty turned to face you.

An elf looking creature and a nymph sat in the boat in uniform and immediately noticed your presence.

"Are you ok? Can we help you?" The nymph said.

"There's a-a ship wreck just past the reef. The people on it, they were murdered!" You panted.

"What?" The elf exclaimed.

"A boat called the skimmer had a huge hole in the hull, and I thought it was just a normal wreck so I went to look at it but there's two bodies! They were trapped behind a locked door and none of the safety gear had been touched. Someone blasted a hole in the hull and locked them in, left them to drown!" You explained.

The two guards immediately knew you were being dead serious from the utter shock you were in, and began to pull up the anchor.

"Radio the office and get the police on the line" the elf said to his partner as he pulled the anchor back into the boat. "And siren, show us where the wreck is"
