Description
In the aftermath of a theft and murder, Martha Radcliffe increasingly suspects her husband George Radcliffe, whose testimony in court convicted the main suspect, of being the real culprit.
Businessman Jason Root is stabbed to death on a night when George and a clerk named Donald Heath are the only other employees working at the office. A mailbag full of money is stolen in the process. George sees Heath in the boiler room when he runs after the murderer right after he hears Root crying after being stabbed; George, who is seen sweating nervously both during the trial and later, insists that Heath must have been the murderer, and Heath is convicted. Several years later, a lost mailbag is found and the Radcliffes receive a long-delayed letter that was in the bag. The letter, which Martha reads, contains a blackmail threat from Jeremy Clay accusing George of the crime.
As the story unfolds, clues pointing to George quickly accumulate. These include a new business he started soon after the trial, using money that he claims to have made in the stock market; his own desperate desire for success; lying to his wife in order to secretly search for Clay; the suspicious new business with an unknown man, Morris Brooke, right after the trial; and Clay's claim, when Martha finds him, that he was an eyewitness to the crime and George was the murderer.
George and Martha repeatedly have conversations in which she vacillates between questioning him and insisting she believes in his innocence, and he alternates between insisting that she believe in him and telling her to make up her own mind. Tension is built by the repeated appearance of George's old-style shaving razor, his insistence that Martha join him at the edge of a cliff, references to his masculine virility and his warning that Martha's investigation could threaten his business.
At the conclusion, Clay tries to kill Martha after being seen sharpening George's razor. George rescues his wife just in time and subdues Clay as the police arrive.
