Murdoch Mysteries Wiki

"The Keystone Constables" is the ninth episode of the eighth season of the Murdoch Mysteries and the one hundred-fifth episode of the series. It first aired on December 8, 2014.


A vaudeville-inspired murder mystery featuring a scene with Crabtree and Higgins impersonating Murdoch and Brackenreid in an undercover two-act.

Detective Murdoch investigates shooting of vaudeville comedian Bert Grady who is found dead on the street, shot three times in the chest. Grady had just finished his performance at the Bradley Theatre, with Constables Crabtree and Higgins in the audience. The shooting looks like - or was made to look like - a robbery. He was not well-liked by others in the show, including a young juggler by the name of W.C. Fields and Ed Ward, Grady's one time comedic partner who is now far less popular on his own. The police find Grady's hotel room ransacked and suspect someone may have been out to steal his jokes. Would-be comedians Crabtree and Higgins join the show undercover and quickly identify Grady's mistress, Eleanor Moffat, wife of the show's manager, Lewis Moffat who became aware of their affair a week ago. A buried body gives them the clue to solving the crime.

Historical References

  • In reality, W.C. Fields was considered to be the best juggler in the vaudeville circuit throughout the United States when he was only 21 or 22. He was fairly famous as a juggler before he becoming a famed comedian and film star.
  • The Whoopee Cushion existed at the time and at one time was known as a "flatulence sack".


  • Filmed in the Cathedral at the Scottish Rite Club, Hamilton.
  • MM writer Jordan Christianson wrote Bert Grady’s monologue using mother-in-law jokes that go back decades to serve the plot of the story. The other monologues heard throughout the course of the episode he found at the Toronto Reference Library; they are actual monologues of the period and weren’t attributed to any particular performer of the time


  • Higgins is hit with a tomato on the lower part of his scapula while leaving the stage, but it's suddenly atop his shoulder when he cleans it off backstage.
