Witness For the Prosecution
Based on a short story by Agatha Christie, The Witness for the Prosecution is a rare Christie work in which the murderer escapes punishment. In the end, Christine (Marlene Dietrich) reveals the shocking truth: Leonard (Tyrone Power) was guilty, but she loved him enough to save him from a worse fate. After being told by Sir Wilfrid (Charles Langston) that "no jury would believe an alibi given by a loving wife," Christine purposely implicated her husband on the stand, knowing it would work in her favor.
