Satan Met a Lady

Private detective Ted Shane (Warren William) is thrown out of yet another city and returns to work with his former partner Ames (Porter Hall), who is not particularly happy to see him, because his wife, Astrid (Winifred Shaw), is in love with Shane. A new client, Valerie Purvis (Bette Davis) wants the help of the detectives in finding a man called Farrow, and Ames and Farrow both end up dead, with Shane the chief suspect for both murders. After demanding the truth from Valerie, Shane finds that his office and apartment have been ransacked, and his secretary, Miss Murgatroyd (Marie Wilson) locked in the closet, by Anthony Travers (Arthur Treacher). Travers is searching for "Roland's Trumpet", an 8th century ram's horn rumored to be crammed with jewels, which Shane suspects is what Valerie is after as well. Madame Barabbas (Alison Skipworth), a notorious criminal, is also searching for the horn and sends a gunman to bring Shane to her. Working all sides of the street, Shane makes deals with each of them to find the horn, and eventually winds up in possession of the package supposedly containing it -- but it turns out to be full of sand instead of jewels...
