"Detective Amanda, are you busy at the moment?" The voice of her police commander passed through her ears. Amanda turned around and looked at the commander.

"What's wrong this time, commander?" She asked with a plain voice.

"There is a murder that happened just thirty minutes ago. I need you to head onto scene with your team to check it out." The commander sat on the seat in front of her. "Be careful when you get there. The killer could still be lurking around."

"I will be cautious." Amanda said confidently and swallowed a gulp. After collecting the evidence, she met up with her partner, Lu Han. Taking her phone out, she dialed a number and hit the call button. After a few beeps, there was a shaky voice through the phone: "Hello Amanda is something wrong?"

"Yoona, I'll be at your apartment in twenty. There is a killer on the loose." Amanda hung up the phone and told Lu Han her instructions. After a while, Amanda disappeared into the elevator.
