 Father Dominic, the only priest on duty that night in the monastery where Amanda is having a retreat, is first approached by a female friend from his youth who insists he sees someone after many years, and then by Leonard Wilson, the grounds-keeper, who insists to have his confession heard immediately- a murder that day! Steve finds father Dominic bend over the corps of Matthew Scarborough. Monsignor D Amico, who knows the Sloanes since long, asks Mark to find the real killer as it can t by Dominic; he goes in as a handyman -inspired by his disastrous attempt to practice pluming by a book  by numbers - and learns father Dominic was the friend since childhood of the victim, till they both dated Matthews present widow; and Leonard is one of father Dominics protégés: ex-cons he gave a first job after release. Though convinced Matthew must be the killer, how can the Sloanes prove it?
