In the 1960s, crime writer Jonathan Goodman made inquiries that led him to a junior employee at Prudential who had worked with Wallace. This man had done some of Wallace's collection work for him when the older man had been ill in 1928. Wallace had then had first-hand evidence that the younger man did not pay in all the premiums which he had collected. Yet for whatever reason, Wallace did not seem to have passed this information on to his employer. About a year later, the young man left Prudential to join another insurance firm. Wallace was later told that while this man had not been sacked he had left under something of a cloud, his father making up some of his son's shortfall. The young man was also acquainted with Julia. Goodman mentioned him, but not by name, in his book "The Killing of Julia Wallace".
