Helen Nielsen

An American in London, down on his luck, runs into a beautiful blonde in a bar who offers him a lot of money to marry her. Broke and unemployed, he takes her up on it. When he wakes up the next day, he finds himself in a strange room that turns out to be an artist's studio, there is blood on his coat, and he discovers that his new "wife's" father had been murdered the night before.
