Nocturne (RKO Radio), featuring George Raft as a deadpan detective, gets by in a superB way, but it will add no gloss to Producer Joan Harrison's shiny reputation (Phantom Lady, Uncle Harry).
The case of the dead composer looks like suicide, but Detective Raft knows better. First, his stubborn talk of murder gets him bounced from the Homicide Squad. Then his continued detecting, without pay, gets him shadowed by a sinister fat man, beaten up, involved with an enigmatic lady (Lynn Bari) and eventually hunted by the cops.
Nocturne has some minor virtues for whodunit...
