"Why are you here?"

　　Xia Meilin was glaring at the woman who was sitting on the shotgun seat of the car.

　　"I'm on a month vacation so I decided to spend it here." Nian Jiezhen said with a smile on her lips.

　　Xia Meilin turned to Lu Yifeng with eyes asking for the truth.

　　"I'll tell you later." He patted her head gently as if he was trying to calm her down. "Su Lei, to Red Garden."

　　"Yes, sir." Su Lei started driving to the place where they will be having their dinner.

　　"To have a vacation for a month, aren't you usually busy?"

　　"Well, it's not a total vacation. I am a.s.signed here to check on a case."

　　"A case?"

　　"Yes, Interpol is after an international serial killer. I am one of the special agents a.s.signed here to help your law enforcement to investigate the case." Nian Jiezhen explained.

　　A sparkle appeared in Xia Meilin's eyes since what she said caught her attention. "How were you able to find out that the killer is in this country?"

　　"Because of that killer's signature."

　　"Signature?" Xia Meilin asked with a confused look on her face.

　　"Signature connotes artists signing their work with a triumphant flourish. The killer's signature, in contrast, is more like an imprint left behind, especially on botched incidents. It can be the result of psychological deviance, but some are just for effect. Some offenders have posed a corpse in a provocative s.e.xual position, carved something on a body, inserted items, or taken a souvenir. It's thought that signatures originate with personality factors rather than arising from what's needed to complete a murder."
