Chessman

From publisher blurb: Tracking down people is nothing new for most private investigators, but when your subject turns out to be a renegade wizard you never know what you might find. In Greg Brandt's case, he found a collection of enchanted game pieces that granted him the ability to channel appearances and abilities reflective of the game of chess. Now, he brings his hard-boiled sensibilities to the streets as the super-powered and often unpredictable hero, the CHESSMAN!
