Writing in the "Sunday Times Magazine" in October 2013, P.D. James refers to the conclusions of Goodman and Wilkes, but speculates that Parry made the "Qualtrough" call as a practical joke in retaliation for Wallace's having reported Parry to their employers for dishonesty. She concludes that Wallace did in fact murder his wife and speculates that the murder weapon was an iron poker with which Wallace struck his victim, having first stripped and covered himself with the mackintosh found at the scene, spattered with Julia's blood, and that it was entirely possible for him to have done so within a reconstructed timeline of the events of that evening. She believes that "in the end justice was done, if only the fallible justice of men". This reading of the evidence must, however, be set against the fact that Wallace probably never reported his experience of Parry's dishonesty to their mutual employer and that Parry was not formally dismissed either at the time, or later. There is no evidence that Wallace attempted to use this information to coerce or blackmail Parry.
