Inspector Proby's Christmas — John Gano

Snow is falling in Hampton and the city's inhabitants are busy with festive preparations, when a young woman is savagely murdered in the city's picturesque cathedral. Inspector Proby is assigned to the case. Now he faces his own nightmare before Christmas: As the bodies begin to pile up, he is haunted by his own wife's infidelity, and wonders if she might even be involved in the murder.
With the superintendent away on holiday, and the Chief Constable threatening suspension, Proby is not even sure he can rely on his own men. In the end, everything depends on a vital clue, and the inspector, certain that he knows the identity of the killer, must act as bait for his prime suspect.
