it depends which way you look at them - and you are avoiding questions as usual.
to me it is the diary of a homophobic person who was determined to get his man because he did not think he belonged in the family - and wanted him cut out of the inheritance from Granny speakman whether found guilty or innocent. He made it clear the fact that he was adopted was relevant and none of the conversations are verified by third persons.He was not prepared to listen to experienced officers and went further up the line until he got what he wanted .Strange his wife kept well out of all this.
Jan, leaving aside Jeremy's guilt or innocence, I entirely and absolutely concur with what you say. It WASN'T a diary. It was an excuse to pour out all the rage, envy and hatred he'd felt for Jeremy since Jeremy's infancy. I read through, very carefully, what purports to be a diary and it reminded me of the style in which Ann wrote of Sheila, which contained the same envy and resentment, both father and daughter putting HUGE emphasis on FAMILY money to which they seemed to believe neither child was entitled. It compounds my belief that Neither Jeremy nor Sheila were seen as a welcome addition to the family by anyone but Nevill, June and, possibly, Pam.
