A Novena for Murder — Carol Anne O'Marie

Heaven knows nobody expected a homicide at Mount St. Francis College for Women in San Francisco. Sister Mary Helen, at seventy-five, had resisted retiring there for fear she'd find only prayer, peace, and a little pinochle. But she'd barely arrived when she was greeted by an earthquake, a hysterical secretary, and a fatally bludgeoned history professor.

The police professionals, homicide inspectors Kate Murphy and Dennis Gallagher, promptly made a very human error: They arrested an innocent. As one sister invoked divine aid with a novena to St. Dismas, patron saint of murderers, Sister Mary Helen turned her own talent for investigation into a hunt for the guilty ... and found that nothing is sacred when it comes to catching a killer with a habit for murder.
