There was long since nothing outside the window. The police officers responsibly checked my entire house, and they finally got a clue from the surveillance.
That night, someone had used a drone to dangle something that flew outside my window and hovered there for a long time.
As the police asked me who I had offended recently, Henry and Janet were the first people I could think of.
By the time they were taken into the police station, Henry was bewildered, but Janet was quite calm and even raised her eyebrows at me.
I almost immediately concluded that it was her.
But when the police questioned Janet, she denied it entirely and had an alibi.
As Janet was leaving, she gestured at me in a provocative manner.
The police reassured me that they would continue to investigate and would let me know if there was any news.
On the way back, I called my assistant and asked her to find someone to help me investigate Janet.
Janet dared to provoke me in public at the police station, so I didn't think she would let it go. I believed that I could protect myself better if I knew my enemy and myself.
The assistant quickly found out the result. She sent the information to me just as I arrived home.
