 This is an unusual episode in that it brings back a murderer Jessica put away -- the very first one, in fact -- in the same role. Preston Giles, who published Jassica s first book, was subsequently sent up on her evidence after he admitted to killing a business rival who had ruined him and set him up on bogus theft charges (he also killed another suspect as a red herring). Double life sentence for murder? You d think so, but Preston Giles gets a Get Out of Jail Free card after only six years behind bars. The circumstances are such that even Giles himself is looking over his shoulder to see who might have pulled strings to get his convictions overturned (nobody will admit to it). Giles goes back to his old job at the publishing house (again for reasons not clear to anybody) and starts editing Jessica s work again. But before he committed the murders, Giles had feuded with another editor, who is still at the firm -- but not for long, as he is swiftly slain. Either Giles committed murder number three or is the patsy in an extremely elaborate frame-up designed solely to pin the crime on him. Arthur Hill gave his last-ever performance (for once not getting "Special Guest Star" billing) in the title role.
