The officers were satisfied. My manner had convinced them.

I think that this quote can be very decieving. The narrator thinks that he has the murder in the bag and that no one knows it was him, but if you think about it, why would the officers stay at his house to chat with him? The officers must have known something was wrong or else they wouldn't have stayed. The officers were waiting for the narrator to crack and admit that he was responsible for the crime.
