From The Perry Mason TV Show Book (Revised)
Former beauty queen Mary Ann Mobley plays Sharon Carmody, a model trying to become the new representative for White Snow soap. Trouble is, the job calls for Sharon to be as pure as the product she’ll be pushing, and unfortunately, her past is getting in her way. She’s being blackmailed. Then her boyfriend, ex-boxer Duke Maronek, fights with her adversary, and when it is over, the adversary is dead, and it looks like smooth sailing for her. But Duke confesses to Perry, and when the police arrest someone else for the crime, Perry is torn between two unpleasant options. Ethics prevent him from revealing his client’s confession, but he can't let an innocent man be convicted.
