Former private detective Molly Murphy Sullivan and her policeman husband, Daniel, have built quite a life for themselves in Greenwich Village. They have a good marriage, a true partnership where they value each other’s opinions in all things. So when he tells her they’re moving to a fancy home on Fifth Avenue --- and that he’s running for the sheriff of New York --- Molly is left reeling. Daniel begs Molly to trust him. But why would he run for sheriff on the Tammany ticket? A party known more for kickbacks and quid pro quo than anything else, it used to be everything Daniel despised. So what’s changed? And why didn’t he discuss it with her beforehand? Molly can’t help but wonder what Daniel has gotten himself tangled up in…and if he needs her help to get out.

Now that she’s no longer a private detective, Molly Murphy Sullivan is looking forward to a time of settled tranquility with friends and family. Back in New York, where her own story began, Molly decides to accompany some friends to Ellis Island to help distribute clothing to those in need. This journey quickly stirs up memories for Molly. That evening, her policeman husband, Daniel, comes home with a tale to tell: there was a murder on Ellis Island that day, and the main suspect is the spitting image of Molly. The circumstances are eerily similar to when Molly herself arrived on Ellis Island, and she can’t help but feel a sense of fate. Molly was meant to be there that day so that she can clear this woman’s name.
