Donald Hamilton
Donald Hamilton was a U.S. writer of novels, short stories, and non-fiction about the outdoors. His novels consist mostly of paperback originals, principally spy fiction but also crime fiction and Westerns such as The Big Country. He is best known for his long-running Matt Helm series (1960-1993), which chronicles the adventures of an undercover counter-agent/assassin working for a secret American government agency.
Hamilton began his writing career in 1946, fiction magazines like Collier's Weekly and The Saturday Evening Post. His first novel Date With Darkness was published in 1947; over the next forty-six years he published a total of thirty-eight novels. Most of his early novels whether suspense, spy, and western published between 1954 and 1960, were typical paperback originals of the era: fast-moving tales in paperbacks with lurid covers.
