The Blue Dahlia

When Johnny Morrison returns home at the end of the war, he expects to receive a warm welcome from his wife. However, he makes the unpleasant discovery that she's been unfaithful to him with Eddie Harwood, the owner of the Blue Dahlia nightclub. After a heated and violent argument, he storms out of their house. Later that night, she's murdered--and Johnny winds up the prime suspect. Now, to prove his innocence, Johnny must find the real culprit. Among the suspects are the ruthless nightclub owner and a vicious gangster. Joyce Harwood, the estranged wife of the club's proprietor, lends Johnny a hand and the two fall in love while tracking down the killer. Two ex-service buddies also come to Johnny's aid: the shell-shocked Buzz Wanchek and George Copeland. Will Johnny solve the mystery before the police find him and charge him with murder?
