The May Day Murders is a mystery novel by Scott Wittenburg, made available as a free podcast audiobook.
The autumnal tranquility of Smithtown, Ohio is shattered when Dr. David Bradley arrives home to find that his wife has been raped and murdered by an intruder who has left no clues behind except the words May Day painted in lipstick on his victims body. When the police later learn that another Smithtown resident has been raped and strangled in New York City, it becomes frighteningly clear that a cunning serial killer targeting Smithtown women is on the prowl. Newspaper reporter Sam Middleton is determined to help Detective Roger Hagstrom track down the assailant of his ex-wifes best friend and everyone is asking the same question as the mystery unfolds: Who will the killers next victim be?
