 However, the police suspicion that Adams had injected Hullett with a lethal dose of 5 grains of morphine at 10.30pm on 13 March was disproved at the committal proceedings when the prosecution's medical expert witness admitted in cross examination that, as Mr Hullett had received a morphine injection about eight hours before his death but had woken and talked to a nurse half an hour before his death, the injection could not have been as much as 5 grains and the death was probably from coronary thrombosis, as Adams had certified.Gertrude Hullett, 50, became depressed after Jack's death, and Adams prescribed sodium barbitone and sodium phenobarbitone for her.Several of her friends and her household staff later told the police that she appeared to be drugged, and claimed that they had urged her to leave Eastbourne and Adams' care.
