Where does all the information about Sheila changing her mind at Christmas 1984 come from? As for her stay in hospital in March 1985 I go on what she wrote to Ann Eaton,which was uncannily similar to the remark she made in her diary that fatal week at White House Farm:"I didn't mean to be horrible to Jeremy.."
Steve, I have to be honest and say that other than reading it here very recently, I don't know where the information came from, but neither do I recall that there was anything in the letter to AE which could be described as being "uncannily similar" to words she wrote in her diary some 12 weeks later.
