before he was arrested. Before the trial Case selection Charles Hewett, Hannam's assistant, was quoted as saying that both officers were astounded at Manningham-Buller's decision to charge Adams with the murder of Morrell, since her body had been cremated and therefore there was no evidence to present before a jury. This assertion was published after the deaths of both Hannam and Manningham-Buller. This shows a misunderstanding of the principle of corpus delicti, and his assertion that traces of drugs found in exhumed remains were more compelling as proof against Adams was disputed by Devlin, as the exhumations and subsequent post-mortems yielded nothing of interest. and as the pathologist concerned did not consider that the levels found were significant. Cullen also describes Morrell as "the weakest" case of the four the police deemed most suspicious. Devlin, who regarded none of the cases mentioned by Hallworth as being as strong as the Morrell case, despite it being six years old, suggested that, in an investigation covering a ten-year period, the police were unable to find a better case than the Morrell one. In 1957, it was the job of the police to investigate reported crimes, to determine if one had been committed and arrest a suspect. It was then the job of the Director of Public Prosecutions (DPP), or in very serious cases of the Attorney-General or Solicitor-General, to review the police case and decide whether to prosecute and, in more serious cases, what offences to prosecute. What to prosecute depends on legal issues and Devlin states that, to succeed in the murder case against Adams, the prosecution had to show, firstly, there had been an unnatural death, secondly, an act by Adams was capable of being murderous (such as an injection so large as to cause death) and finally Adams's intent to kill. The Attorney-General thought he had evidence that Adams had prescribed large quantities of opiates to Mrs Morrell, Adams's own admissions that he had used them all on Mrs Morrell and injected all or almost all of them himself, and a medical expert's testimony that the only possible reason to inject so much over a short time was to kill her. Cullen mentions Mrs Morrell, Mr and Mrs Hullett, Clara Neil Miller and Julia Bradnum as cases that Hannam regarded as warranting prosecution. However, in the cases of Mr Hullett, Clara Neil Miller and Julia Bradnum there was no
