The case against Parry is much stronger than that against Wallace, and ascribes a more convincing motive. There was witness evidence of a blood-stained glove found in Parry's car on the night of the murder, when he took his car to the garage for cleaning. The evidence from the man who cleaned the car was deliberately suppressed by the police at the time. Wilkes argues that there was, moreover, no motive or reason for Wallace to kill his own wife, and that he was charged because the immense publicity surrounding the case impelled the police to get a conviction at any cost. Parry died in 1980 without admitting any involvement in the crime. However, when Goodman and his friend Richard Whittington-Egan confronted him on his London doorstep in 1966, Parry displayed an astonishingly detailed knowledge of the case, and was aware of the deaths of several obscure witnesses connected with it.
