Storyline:

Scene of the Crime (1949) Homicide detective Mike Conovan investigates the shooting of fellow detective Monigan...who apparrently was moonlighting as guard for a bookie. He finds that all the bookies in town are being robbed, most upsetting to the racket bosses who can't get normal police protection. Mike encounters blind alleys and double crosses, and is distracted by his wife's growing disenchantment. Lots of police slang.
