"Twisted Sisters​" is the tenth episode of the sixth season of the Murdoch Mysteries and the seventy-fifth episode of the series. It first aired March 18, 2013.


Detective Murdoch investigates the death of a young woman, Judith Winslow, found on the waterfront by lads from the Toronto Athletic Club on a training run. Dr. Grace determines the young woman died from drowning though she was struck on the head before going into the water. She worked as a secretary at a financial firm run by Alvin Storey but had ambitions to be a journalist. According to her roommate Sophia Lucas, she had no enemies. The police soon have a second murder when Ethel Morgan is found dead in a alleyway - also having drowned. A third victim, Virginie Rousseau, is found before Murdoch finds the connection between the three – which turns out to be the suicide of another female university student a few years earlier.

A champion croquet player for two years running, Emily Grace returns to the athletic club after hearing that Canada will be sending a croquet player to the Paris Olympics and a past rival is competing. Once Emily had broken off her engagement, she was not welcome at the club; the social snobbery is still very present.
