of missing women in London during his period of activity. Michael Eddowes suggested that Christie had been in a perfect position, as a special police constable during the war, to have committed many more murders than have been discovered. The historian Jonathan Oates considers it unlikely Christie had any further victims, arguing he would not have deviated from his standard method of killing in his place of residence. Innocence of Timothy Evans Following Christie's conviction, there was substantial controversy concerning the earlier trial of Timothy Evans, who had been convicted mainly on the evidence of Christie, who lived in the same property in which Evans had allegedly carried out his crimes. Christie confessed to Beryl's murder and although he neither confessed to, nor was charged with, Geraldine's murder, he was widely considered guilty of both murders. This cast doubt on the fairness of Evans' trial and raised the possibility that an innocent person had been hanged. The controversy prompted the Home Secretary, David Maxwell-Fyfe, to commission an inquiry led by John Scott Henderson QC, the Recorder of Portsmouth, to determine whether Evans had been innocent and a miscarriage of justice had occurred. Henderson interviewed Christie before his execution, as well as another twenty witnesses who had been involved in either of the police investigations. He concluded that Evans was in fact guilty of both murders and that Christie's confessions to the murder of Beryl were unreliable and made in the context of furthering his own defence that he was insane. Far from ending the matter, questions continued to be raised in Parliament concerning Evans' innocence, parallel with newspaper campaigns and books being published making similar claims. The Henderson Inquiry was criticised for being held over too short a time period (one week) and for being prejudiced against the possibility that Evans was innocent. This controversy, along with the coincidence that two stranglers would have been living in the same property at the same time if Evans and Christie had both been guilty, kept alive concerns that a miscarriage of justice had occurred in Evans' trial. This uncertainty led to a second inquiry, chaired by High Court judge Sir Daniel Brabin, which was conducted over the winter of 1965–1966. Brabin re-examined much of the evidence from both cases and evaluated some of the arguments for Evans' innocence. His conclusions were that it was "more probable than not" that Evans had killed
