In Ralph McInerny's Requiem for a Realtor: A Father Dowling Mystery, the 23rd entry in this reliably entertaining series (Her Death of Cold, etc.), the devoted priest of St. Hilary's parish receives an unexpected call from realtor Stanley Collins, who confides that his wife is having an affair with a loyal parishioner and prosperous dentist. When Collins turns up dead in the parking lot of a popular nightspot, the police investigation reveals many possible suspects, all with motive and opportunity. In the best tradition of Agatha Christie, McInerny keeps the reader guessing to the end. .
