Chasing the Murderer for Twenty Years

After twenty years of tracking, the killer is still at large. I thought I would never have a chance to catch him in this life, but one week before the expiration of the prosecution period, he finally showed his weakness. This time, I will absolutely, absolutely not let him escape again. I will use these seven days to catch him! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
