When a vicious alcoholic dies in a suspicious house fire, Rev. Olympia Brown and Father Jim Sawicki stretch the boundaries of their religious vows to prove his death is accidental and not murder. But evidence to the contrary is mounting and the curious clerical twosome have little time to learn the truth and prevent the daughter that the man abused for years from ending her own life. Olympia and Jim confront unspeakable realities of incest, domestic violence and dark family secrets set against a tapestry of misconstrued Catholic dogma and the Irish culture of silence as the two colleagues struggle to untangle a hideous web of shame, guilt, and broken lives. And through all of this, Olympia continues with the restoration of her antique home in Southeastern Massachusetts. Miss Winslow, Olympia's nosy and outspoken house-ghost, begins to reveal more of her own story. Olympia's search for her lost daughter takes a curious turn. Frederick Watkins, Olympia's gentleman friend from England is planning a purposeful return visit. And Father Jim Sawicki, Olympia's partner in amateur sleuthing and best friend forever, struggles with issues from his own tragic past.

When Olympia Brown is invited to attend a religious conference in England, she soon discovers there is more than faith on the agenda. Someone on staff has a well-calculated plan to destroy The Moorlands, including the great stone house itself. Olympia discovers embezzlement, tainted food and a prescient housecat named Thomas, all of which eventually fit into a pattern—but not before she falls victim to a killer's twisted plot. With Father Jim in the States, Frederick must assist his lady wife in this page-turning tale of hatred and revenge.

Chaplain Olympia Brown learns that a homesick freshman is being recruited by a shadowy religious cult. In a race against time, she and colleague Father Jim Sawicki, uncover murder, illicit sex, and the dark side of human behavior, as they fight to expose the Deadly Mission of the Boston Christian Common Fellowship. The psych/thriller spirals into a menacing tangle of religious hypocrisy and greed, as a woman minister and a gay priest, assisted by Olympia's intrepid house-ghost, Miss Winslow, risk their lives to save the innocent girl and put an end to the cult's ungodly business forever.
