I've read about some people who say they used to write to Jeremy and receive letters from him, but they said that he became evasive at certain questions, and that led them to be suspicious or it convinced them that he was guilty.
What kind of thing are they talking about? Is it stuff like - how he thought the silencer got blood on it, or how it ended up in the gun cupboard?
Is it personal stuff about his life or his feelings?
If it's the latter, isn't it natural that he would be evasive? After all, several of his letters have turned up in public, so those who received them obviously don't think they should be private.
