One important fact was not brought up in Evans's trial: two workmen were willing to testify that there were no bodies in the wash-house when they worked there several days after Evans supposedly hid them. They stored their tools in the wash-room (a small outhouse measuring ) and cleaned it out completely when they finished their work on 11 November. Their evidence in itself would have raised doubts about the veracity of Evans's alleged confessions, but the workmen were not called to give evidence. Indeed, the police re-interviewed the workmen and forced them to change their evidence to fit the preconceived idea that Evans was the sole murderer. The murderer, Christie, would have hidden the bodies of Beryl and Geraldine in the temporarily vacant first-floor flat, and then moved them to the wash-house four days later when the workmen had finished.
