It's Terrible

I am a detective and I have solved a large number of cases, and every case is very simple! But until I encountered that case, it was the most difficult case I had ever solved in my life. This case was more difficult than I imagined. I didn't expect that this case was connected to a large number of characters? Not brainless, no heroine, detective, multiple twists! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
