Requiem for a Realtor — Ralph M. McInerny

Father Dowling, respected by all, is well-known for being willing to lend a helping hand whenever he can. So it's no surprise when Stanley Collins shows up at the St. Hilary rectory to confide in Father Dowling about the troubled marriage of one of the church's parishioners. Dowling promises to do his best to find a way to help, but it soon becomes too late. One of the parties involved is viciously killed in a hit and run car accident.

Is it murder? Dowling knows there is good reason to suspect it might be, but when his friend, Detective Phil Keegan, labels it an accident, Dowling 's hands are tied. It's a question of ethics. Unable to break Collins's confidence, he can only keep tabs on the investigation from afar. While searching for the truth, Dowling must protect the secrets of his parishioners at all costs.
