Thanks Gringo
I think the note dated 11th Sept could have been the family chasing up the report / news on the silencer so around that time then .
Interesting .
Perhaps the family felt they were getting nowhere and needed someone else to back them up .
The timing is as you say interesting Jan.
The relatives were getting very busy during this period. According to Colin's statement of 11/9/85,
"... on 9/8/85 I received a phone call from DB to the effect that "we" had all been making statements to the police and we are sure that Sheila couldn't have pulled the trigger."
I believe that this is the same call that Colin described in his book as being the most "disturbing and evasive call" he had received in his life.
From about the 8/9/85 onwards the relatives were making new statements, had co-opted the assistance of Robert Carr who was arranging meetings with EP Inspectors, DB was making unsolicited calls to Colin in a clear attempt to influence his evidence by convincing him, amongst other things, that Sheila "couldn't have pulled the trigger.
Colin's statement of the 11th also mentions legal action being threatened by the Pargeter's over three valuable items that Uncle Neville had "promised". Jeremy received a solicitor's letter demanding the items or that legal proceedings would follow. The items were allegedly the three most valuable items in the house(two paintings and the third item unspecified). Funnily enough the items were not "promised in Uncle Neville's will".
It is pretty clear, to me at least, that the driving force of the relatives was money and self preservation. They were money chasing before the bodies were even cold.
