Jay Hector MacLarty was an American entrepreneur and novelist known for his thrillers featuring professional courier Simon Leonidovitch. Born in Spirit Lake, Iowa, he spent his early years in Iowa, Nebraska, and Minnesota. By the age of thirty, he had owned restaurants, nightclubs, and liquor stores before founding a series of retail stores and a software company. He also developed one of the first computerized handicapping programs for thoroughbred racing.
MacLarty later turned to fiction writing, taking a break from his software business to pursue his passion. His first novel, a thousand-page manuscript, remained unpublished, leading him to focus on writing commercially appealing thrillers. This resulted in a four-book series published by Simon & Schuster: The Courier (2003), Bagman (2004), Live Wire (2006), and Choke Point (2007). Each novel was nominated for a Barry Award, with Bagman receiving a starred review in Publishers Weekly.
Beyond writing, MacLarty was an active leader in the Las Vegas Writer's Group, helping aspiring writers advance their careers.
