Attending a conference in a seaside town, he has yet another supernatural encounter, this time with a murdered girl who worked at a local massage parlor. Details of the murder lead Father Gilbert to approach the police with clues in common with other cases, bringing him into contact with a detective from his days with Scotland Yard.
Meanwhile, a local monastery has been vandalized, with grotesque images and profane graffiti defacing the altar and walls. The head of the monastery accuses the local sex-trade industry of retaliating against his outspoken stand against it. Then, one of the brothers at the monastery is found dead in the local red-light district. All evidence points to his having been a regular at a massage parlor--the same one where the murdered girl had worked.
