Arriving in New York for her childhood friend Tabitha's wedding, Amory Ames and her husband Milo think the trip will be deadly dull, since Prohibition is in full swing. But when a member of the wedding party is found murdered on the front steps of the bride's home, the happy day takes a dark turn. Even as clues point to the handsome gangster Leon De Lora, there may be reason to think that the killer is closely connected to the wedding party. With matrimony marred by murder, Milo and Amory's sixth outing (after An Act of Villainy) also finds them drawn into the glamorous, dangerous world of nightclubs and bootleggers.
