So,Mugford realised Jeremy had carried out his alleged threat of murdering all of his family and tells him to go back to bed,and then SHE herself goes back to bed? Rubbish!
I think she mulled it over in bed and realized that Jeremy had finally gone ahead with his scheme and was no longer crying wolf. You have to remember the incessant practical joker which was Jeremy Bamber which led his Headmaster Mr. Bruce Logie Lockhart,92, to describe him as "a relentless tease". An unsophisticated Julie,the product of one of the best
all girl grammar schools in the North of England was unaccustomed to such deviant and infantile male behaviour. The crimes were a combination of circumstances;double adoptees,some parental failings and the avaricious Zeitgeist of the times which meant any unproductive members of society faced the axe,and the temptation harboured in Jeremy's mind finally became too much as he saw a way out from the perceived serfdom which circumstances had engendered,justifying the deaths to himself as people unworthy of life,and the possibility of Colin making a new start no longer having the millstone of children to look after. An imprisoned Jeremy can no longer confess to such wicked crimes without the ultimate retribution which oh so nearly killed him several years ago and which is completely unacceptable,a possible way out through turning to Christianity is closed to him as he reminisces on the perceived damage that religion inflicted on sister and mother,and Jeremy is now stuck as a pathetic figure with a handful of correspondents for succour as he becomes older and greyer,with not even an apology to Colin which might be a start as he contemplates the rest of his life behind bars.
