While out for a stroll, Detective Murdoch and Dr. Ogden soon find they have a murder on their hands when an attractive young woman is found strangled in the park. When Murdoch and Constable Crabtree search the woman's lodgings, they find some very risqué photographs of the young woman leading them straight to a known pornographer, Marcus Evans. He denies having anything to do with the young woman's death but Murdoch is shocked to find photos of Sally Pendrick, whose husband James he has long suspected of criminal activity. Mrs. Pendrick eventually admits to having posed for the photos and that she is now being blackmailed. When Murdoch accompanies her to a meeting with her blackmailer, they are nearly killed but it all seems too easy for Murdoch who thinks someone was out to kill her all along. Dr. Ogden meanwhile is growing impatient with her life. Her romance with Murdoch seems to be going nowhere and she is now seriously considering an offer to practice medicine away from Toronto.
