Max Allan Collins Killing in Comics Novel

"In Manhattan of 1948, a famous former striptease artist named Maggie Starr runs her late husband's newspaper syndicate, distributing the superhero comic Wonder Guy. But when the cartoon's publisher winds up dead, Maggie hunts for the killer among a cast of cartoonists, wives and mistresses, and minions of a different sort of syndicate - a crew of suspects with motives that are far from super-heroic."
