 In response to the defence's production of the nurses' notebooks, Dr Douthwaite, who had initially suggested 8 November 1950 as the day on which an intent to kill could be first deduced, changed this to 1 November.This was because Adams had completely withdrawn morphia injections on 1 November, later reintroducing the drug on the evening of 5 November, which Dr Douthwaite interpreted as a plan to reduce Mrs Morrell's tolerance to morphia, before it was brought back in increasing doses.His new theory was that, rather than a single injection being lethal, all injections of morphia after its reintroduction on 5 November were potentially lethal, and could only have been intended to be lethal, through a process of accumulation.
