Murdoch Mysteries - Season 3 Episode 12 : In the Altogether

Murdoch is drawn into the naughty world of Victorian erotica and blackmail when he investigates the murder of Abigail Tunstall, a young woman who had been posing for salacious photographs. Interviews with Abigail's friends and family and the discovery of one of her erotic photos help Murdoch zero in on the location where the pictures were taken – a studio owned by a photographer named Marcus Evans. When Murdoch searches through photo collections for clues to Abigail's murder he makes a startling discovery – one of McHugh's erotic models is none other than Sally Pendrick, the vivacious and beautiful wife of Murdoch's nemesis, the rich and powerful industrialist James Pendrick.
