Carol received "hundreds" of neatly handwritten letters in total from Bamber — some up to 25 pages long — and says most of them were him repeatedly claiming his innocence.
She adds: “He did go into great depth on some issues which were always what he wanted to talk about — (what he claimed was) police corruption and withholding of evidence and so on — but when I tried to draw him out on anything more personal it was very brief.
He did write in some depth about his relationship with June Bamber and some of that, if you take it on one level, reads very moving. But when you put it into context there wasn’t a lot there.
“I did approach it with an open mind to start with and there was even a point where I did think, is this going to add up? There are always issues with cases, no matter how straightforward, unless the person who committed the crimes is willing to say so.”
Carol says the convicted killer was largely "charming" to her when he wrote.
She says: “He was really friendly, very charming. He was always very polite and he’d talk about other things too from time to time.
“But it always went back to, I remember the phrase he always used was, ‘we now have the key to the door’, or ‘we now have the key to the gate’.
“That happened so many times in his letters. There was always something that he’d found.
“He obsesses about certain key points and he’ll do his best to find a loophole within a certain part of the case, for example the logs of the calls that night or the silencer issue.
“At one point they were talking about five or six silencers involved in the case. Then it was one or two. It just went on.”
