When a dead man's body is found in the upper basin of a historic fountain in Boston Common with a cryptic message in his pocket, Detective Brooks reluctantly calls in Father Tom and Angelo to help solve the clues in the hunt for a killer set on justice and revenge. Fallen Graces, the fifth book of the award-winning Father Tom series, delves into the psychological and religious complexities of a killer who becomes as equally unpredictable as dangerous to the parish neighborhood of St. Francis, and Father Tom has no choice but to become more involved, risking his own life to find the answer.
