Pay Up or Die

"Manville 'Manny' Moon is one of the great unknown series eyes that somehow slipped through the cracks. He's tough, honest and handy with the wisecracks, but he's a whole lot more. He's pulp, through and through, but he also displays a compassionate side that neatly echoes or anticipates Lew Archer, Dan Fortune et al." -- thrillingdetective.com
