Amos Walker

Amos Walker is a fictional private detective in a series of more than thirty novels and short stories written over the course of five decades by Loren D. Estleman. Publishers Weekly has called author Estleman "arguably the finest practitioner of hard-boiled private eye fiction with his Amos Walker novels," and the series has won multiple Shamus Awards from the Private-Eye Writers of America, including a Lifetime Achievement Award for the author.
Walker works in Detroit and lives on the Detroit-Hamtramck border. A Vietnam veteran who boxed in college and served as a military policeman, he is sharp and streetwise. Like all good private investigators, Amos has an independent and pugnacious streak: While still in the police academy, he was fired from the Detroit Police for punching out a creepy but connected fellow cadet in the shower. On his first appearance, in Motor City Blue, Amos is in his thirties, and he ages over the course of subsequent novels.
Amos Walker is a traditionalist. As one reviewer noted:
