When she finds her priest murdered, Molly Malone, secretary of their Catholic parish, vows to never let it happen again. She'll use the full force of her Irish will, and her previous stint on the Irish police force, to protect the new priest from the congregation's rumors of criminal activity. Falling in love wasn't part of her plan. However, young, handsome and - dare she even think it? - flirtatious, Father Tim O'Rourke is nothing she expected. But Father Tim is also nothing like he seems to Molly: he's Special Agent Zach Saint, an LDS FBI agent undercover to root out the mob that's hiding in the parish. And Molly isn't helping: every time Zach gets close to the mob, Molly manages to get in the way. Falling for her is the last thing he needs. Now Zach must find the murderer and catch the mobsters before his feelings for Molly blow his cover and add another murder or two to the mobsters' docket.
