Fall Guy — Joe Barry

A lovely young heiress of psychopathic tendencies, a young man who died incognito, a bewitching red head who wanted protection, a couple of killers looking for a fortune in emeralds ....
One queer case after another, and they all spelld sudden death!

By some queer coincidence Rush Henry, hard-boiled private eye, found the whole shebang dumped into his lap .... But was it coincidence? Hardly, because pretty soon they began to fall together in a mysterious and dangerous puzzle and Henry found he'd rather be nursing a keg of dynamite! For he was now, through no chosing of his own, sitting in on a game of death and deception that had started in the Orient and had found his way to Chicago, with the stakes still up and himself marked as the fall guy.

If you like fast, action-packed detective fiction, follow Rush Henry around for a while and you'll get plenty.
