Mrs Bixby and the Colonel's Coat

Mrs. Bixby, living in New York with her husband, goes out of town once a month to supposedly visit her aunt, but really to see a Colonel she's having an affair with. The Colonel breaks up with her and gives her a fancy mink coat as a parting present. Mrs. Bixby has to think of a way to explain the coat to her husband and comes up with an elaborate subterfuge involving a pawnshop. The plan goes wrong in a way that ends with her husband's secretary wearing the coat.
