Odds-On Murder

Doc Connor (a strictly legal operator whose patients, however, range from Broadway's shadiest characters to racehorses) goes corpse-stalking-and winds up operating on a boy with a slug in his belly. The Doc, incidentally, has a gun in his back. And the gun is in the hands of a killer, a basher-in-of-heads-a guy he likes better every day.

Then he hears via the radio and Katie (beautiful Katie!) that he's slated for the next bashing. But any man who's got a girl like Katie on the airwaves has already lost his head . . .

Odds-On Murder was first published in 1948.
