"Oh my God."

She exclaimed, Syrena immediately ran into the new room, threw herself on the bed in the corner, saying:

"I'll take this one."

She smiled gently, turned to thank her grandfather, then closed the oak door, standing close could smell the faint smell of oak in the air. She picked up her things and put them on the other bed, then sat down and looked around the room, exhaling.

"How are you?"

Syrena asked. She replied slowly.

"I feel so sorry. That story just now, I should have told you more."

"Me too. I love that story."

But no matter how hard she tried, she had to get up to get the light from the phone light, pull out a book and start reading. She hoped that reading for a while sleep would find her again and she could fall asleep.

She looked at her watch, it was only one o'clock in the morning, it was too early, she thought to herself, that's all she had to read. So she began to focus on the content and story of the book. At the climax when Sherlock Holmes is about to solve the case, she suddenly hears...
