The Hundred Dollar Girl - William Gault Campbell

When some strongarm hoods try to muscle in on the fight game, hefty Joe Puma is hired to find out who's doing the dirty work.

What looks like a typical rackets murder turns out to be a dangerous deal for the private eye. He tussles with some trigger-happy punks and a couple of lethal beauties.

Then in one quick leap from mattress to mat he finds himself in a clinch with a murderer who's still fighting, still hating, still bent . . . on the kill.
