The Dark Corner

In New York, private investigator Bradford Galt (Mark Stevens (actor)) asks his secretary Kathleen (Lucille Ball) to help him catch a man who has been following him. He does catch the thug (William Bendix), who is carrying identification in the name of Fred Foss and says he was hired by Tony Jardine (Kurt Kreuger). However, his name is actually Stauffer, and he is working for Hardy Cathcart (Clifton Webb), a wealthy art-gallery owner. During the confrontation Stauffer's suit is stained with ink.
