Betrayal on the bowery / Kate Belli.

New York City, summer 1889. Society girl turned investigative journalist Genevieve Stewart and wealthy Daniel McCaffrey have arrived at the docks to see their friends, Rupert and Esmie Milton, off on their honeymoon. But the romantic idyll comes to a screeching halt when a crazed man bursts into their stateroom screaming about demons and drops dead before their eyes. The dead man is Marcus Dalrymple, who had once asked Esmie to marry him, and inside Marcus's pocket, Daniel finds a medallion that they trace to a Lower East Side bar called Boyle's Suicide Tavern. The medallions are prizes given to anyone who spends the night there without dying. Clearly, a visit to Boyle's could prove hazardous, but it may offer the only clue to Dalrymple's death. Genevieve and Daniel barely escape the bar with their lives but learn that the crime could have a connection to the recent disappearance of a sugar baron's daughter. Only after another young man plunges to his death from a rooftop bar also screaming about demons do the pieces of the puzzle begin to come together. The clues lead Geneviee and Daniel far from the city's moneyed environs to a reputedly haunted mansion deep in the Bronx. There, they will confront the truth and the demon at its heart.
