At the police station,it was Alex's apprentice,Officer Davis,who took my statement.
I acted as if I was completely shocked.My body was shaking all the time,and the tears didn't stop.
"Sister-in-law,please accept my condolences.We will definitely catch the murderer.Don't worry,"Davis comforted me.

Just as Davis was comforting me,the door was pushed open,and a policeman rushed in,saying in a fluster,"He...he...he came to surrender."
Davis asked eagerly,"Who?"
"Mark,that serial killer."
Davis quickly looked at me,"Sister-in-law,I'll go and have a look first."
Not long after,Mark and I looked at each other through the glass in the office.We both had no expression.
Mark took all the blame,including the details of each crime.

All of this was hypnotized into him when I was doing psychological counseling for him.I didn't miss any details.
Two days later,all the cases were closed.
Mark was handed over to the court.I never went to see him once.
Because I knew we would meet again.

I went to pay my respects to my mother.
This was the first time since I returned to the country,and maybe it was also the last time.
That day,the weather was very sunny,just like the day my mother left.
I knew my mission had been completed.
I changed my name back to Isabella White.
Because this was the name my mother gave me.
White, a symbol of purity and beauty, holds a special place in my heart.
Finally,I was sentenced to death at the age of 30.
