A lovely young heiress drops dead in a New York hotel. The police only find a small hole and her letter opener. The coroner rules it suicide, but her father doesn’t believe it, and hires Inspector Gryce and his assistant, Sweetwater, to solve the case. Among her belongings—letters signed with initials only, O.B. Who is O.B., and what, if anything, does he have to do with her death?
