Its nothing but a side track.
If I had my way. Anyone claiming to repeat what Jeremy has told them in writing should be obliged to post a scanned image of the letter. Its in the interest of establishing the truth.
Caroline's claims to what is allegedly written in these letters has changed. Not only that but she refuses to post them. To my mind it's deserving of suspicion and distrust.
It's not necessarily a sidetrack. It's actually rather an ingenious discovery by Caroline. Of course if you believe the relatives have lied all the way through you won't accept the explanation come what may. But Jeremy has contradicted himself many times about where he put the gun, whether he fired any shots to scare the rabbits, whether he thought Nevill was injured when he rang, not to mention the downright lies about Sheila having indulged in target practice, being on the "
hard stuff", the fostering saga &c.
It's why he was happy to wag his tongue on 7 August 1985 yet so reticent when arrested on 10 September.
