In 2017, Ann Carlton, in her book "Penny Lane and All That: Memories of Liverpool", describes how her father—the late Sir Stanley Holmes—visited Wallace in his prison cell, at Wallace's request, after he had been convicted. Holmes was then a teenager working for Liverpool Corporation and was friendly with the sons of Wallace's regular chess opponent, a Mr Caird. According to Carlton, Holmes said that Wallace revealed the name of the man he thought was the murderer; it was a man who Holmes knew from Lister Drive School. Holmes stated the suspect was clever but a bad lot, and that some years after the murder he had seen the suspect in the dock; accused and convicted over a different matter. Speculating about Wallace's motives in asking to see her father, Carlton wrote that he may have suspected that the city's local government establishment wanted to protect the son and nephew of one of their own, and that the case against him was brought to do just that. She added that she believed that the young man her parents knew and thought was a bad lot - and very possibly a murderer – was Parry.
