"​Let Loose the Dogs​" is the sixth episode of the first season of the Murdoch Mysteries and the sixth episode of the series. It first aired on February 24, 2008.


Harry Murdoch is drunk and betting on Rat-baiting; he loses. A short time later, the man who running the betting operation is found dead and Harry is lying drunk nearby. Murdoch is quick to believe his father guilty.

As the investigation progresses, Murdoch is extremely dependent on the memories of a young man who, at the time, was thought of as an idiot savant (now savant syndrome). The young man, the son of the victim, is looked after by the wife of the kennel keeper and despised by his father.

Murdoch concludes that the victim had attacked the woman and, in a rage, the savant killed his father.

After Harry Murdoch is released, he and his son talk and Harry explains that he was—and is—a drunk but that he had never hit William or his mother. Harry says he is heading west.
