The Gathering was the twenty-fourth in Kienzle's series of mysteries, featuring Father Robert Koesler as a Roman Catholic priest whose intuitiveness and caring nature have led him to an unusual calling: solving mysteries, mostly of the murderous kind. In this entry, revisit Koesler's adolescent and teen years, to a time when young Catholic men and women were encouraged, even expected, to become priests and nuns, whether or not their vocation was real. We meet his group of six young aspiring religious (four men and two women) who underwent the rigors of the seminary and the convent together. We learn of their individual struggles with their faith, their mentors, and their commitments to difficult choices. And we painfully discover how one member of this group is inflicted with undeserved guilt by an unspeakably cruel superior and how this dooms his life. Now in their seventies, the group gathers together, a reunion of sorts, that is cut short when one of their number is found dead. Suspicions arise, and once again Father Koesler's acumen is called on to solve the puzzle.
