Former US Marine Infantry Captain and historian who now writes noir private detective fiction which reads like a Raymond Chandler novel. He is proud to introduce the toughest Private Eye since Sam Spade...Gunny Mac is a tough Navy Cross recipient who gets terribly wounded on Guadalcanal and becomes the one thing he hates above all else a civilian. He buys a three-dollar book on how to be a private eye and the world will never be the same. Walker knows how to write like a gritty black-and-white movie. You can see the smoke curling from the cigarettes and the one-liners cracking like gunshots. More fun than a Charlie Chan movie!
