Francis Pettigrew

Tragedy at Law follows a rather self-important High Court judge, Mr. Justice Barber, as he moves from town to town presiding over cases in the Southern England circuit. When an anonymous letter arrives for Barber, warning of imminent revenge, he dismisses it as the work of a harmless lunatic. But then a second letter appears, followed by a poisoned box of the judge's favorite chocolates, and he begins to fear for his life. Enter barrister and amateur detective Francis Pettigrew, a man who was once in love with Barber's wife and has never quite succeeded in his profession.

Francis Pettigrew travels to Exmoor for a holiday with his wife - an area in which as a young boy he was traumatized by coming across a dead body on the moor. In an attempt to exorcise this trauma, Pettigrew walks across the moor to the place where the incident occurred - only to find another dead body. Moreover, when he returns to the scene with the police, the body is gone. Did he really see a body, or is it a hallucination conjured up by his return to the scene of the crime that has haunted him since childhood?
