Extreme Reasoning: the Murderer of the Murder Case at the Beginning

Let me put it first. This is my personal opinion. You are right if there is a difference. You, the protagonist, look like a dog on a leash. If nothing else, you are in the hospital with no memory. After the suspicion was cleared, others still said that he was a distinguished guest. This is the distinguished guest who is handcuffed, right? The distinguished guest who doesn't say anything when asked, right? The Riddler, right? He works obediently as a tool for others, and he doesn't care if the salary is so low. This is not just a machine that gives people credit for solving crimes. Oh, the machine needs to be repaired. Your protagonist doesn't need it. Just give him a shout and give it to the stutterer. He will also help people check for leaks and fill in the gaps. What you write is a pure reasoning machine and has nothing to do with people who have their own ideas.
