James “Doc” Connor, back from service in the War, has settled into his apartment-based practice, doctoring his friends in Midtown (both shady and upstanding) and the occasional horse at the tracks, to the bemusement of his radio star girlfriend, Katie Storm, and his NYPD pal, Lieut. Eddie Marsh. When a nervous man asks him to look at a dead body, Doc smells a rat, but can’t resist. Thrust into a murder, Doc has to navigate an angry cop and a desperate gangster as he tries to figure out exactly who killed the victim.
