Perfect Suspect

The night the forensic report confirmed that my father was the real murderer in the cold case seven years ago, I received a text message provoking the murderer. "Your father is a poor imitator." The detective captain ordered me to be suspended for investigation. However, the new criminal psychology consultant came to me privately: "If you want to catch the real 'artist,' you must first prove your father's innocence." I looked at the DNA comparison results just sent from the physical evidence department, and slowly took out the handcuffs: "Mr. Consultant, please explain - why does your DNA appear in the fingernails of the seventh victim?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
