In 1931, Parry was a spoilt young man of 22 who sustained a lavish lifestyle by spending recklessly. Wilkes claims that Parry knew that Wallace's insurance takings for the day would have been in a cash box at his home. Since he also personally knew Wallace's wife, it would have been no trouble to visit her on some pretext once Wallace had been lured out of the house by means of the phone call sending him to a non-existent address. Julia's murder for the insurance takings was somewhat in vain as there was very little in the cash box that day. Parry was visited by the police as part of their inquiries but was given a false alibi by his girlfriend. Wilkes went ahead and named Parry in his radio programme, and later spelled out his case in a book called "Wallace: The Final Verdict".
