Stuart M. Kaminsky (1934-2009) was one of the most prolific crime fiction authors of the last four decades. Born in Chicago, he spent his youth immersed in pulp fiction and classic cinema-two forms of popular entertainment which he would make his life's work. After college and a stint in the army, Kaminsky wrote film criticism and biographies of the great actors and directors of Hollywood's Golden Age. In 1977, when a planned biography of Charlton Heston fell through, Kaminsky wrote Bullet for a Star, his first Toby Peters novel, beginning a fiction career that would last the rest of his life.

Kaminsky penned twenty-four novels starring the detective, whom he described as "the anti-Philip Marlowe." In 1981's Death of a Dissident, Kaminsky debuted Moscow police detective Porfiry Rostnikov, whose stories were praised for their accurate depiction of Soviet life. His other two series starred Abe Lieberman, a hardened Chicago cop, and Lew Fonseca, a process server. In all, Kaminsky wrote more than sixty novels. He died in St. Louis in 2009.

Ed Gorman (b. 1941) is an American author best known for writing mystery novels. After two decades in advertising, he began publishing novels in the mid-1980s. While using the pen name Daniel Ransom to write popular horror stories like Daddy's Little Girl(1985) and Toys in the Attic(1986), he published more ambitious work under his own name, starting with Rough Cut(1986). A story about murder and intrigue inside the advertising world, it was based on his own experience, and introduced Midwestern private detective Jack Dwyer, a compassionate sleuth with a taste for acting.
Gorman's other series characters include Robert Payne, a psychological profiler, and Leo Guild, a bounty hunter of the Old West, but his best-known character is probably Sam McCain, a gentle young sleuth of the 1950s, who first appeared in The Day the Music Died(1998). Besides writing novels, Gorman is a cofounder of Mystery Scenemagazine.
