Murdoch Mysteries Wiki

"Excitable Chap" is the ninth episode of the tenth season of the Murdoch Mysteries and the one hundred forty-first of the series. It first aired December 5, 2016.


Murdoch strives to apprehend a lecherous costumed criminal known as The Lurker.

Inspector Brackenreid returns after seeing some exciting things at the World's Fair in St. Louis, making him wonder if there’s more he missed.

Murdoch and Crabtree inform the Inspector that The Lurker has resurfaced. His petty theft, destruction of property and tempting of women began shorty before the Inspector left for St. Louis. Murdoch points out, like with any criminal, the severity of his crime could increase. "Put the kettle on, Crabtree."

Every evening there is a Lurker incident: After his thwarted attack of Lydia Hall who stabs him with a hat pin,  he burgles the Brackenreid's home, scaring Margaret and stealing Pendrick's swords.

When popular Gerard Waldkirch, known by all as the Sausage King, is found dead by his toppled sausage stand - the cause of death a very deep knife wound - witnesses can not give much of a description, but it was the Lurker. Crabtree reports that they saw a man cloaked in darkness who snarled like an animal –  the Lurker has moved up to murder.

Character Revelations

  • Realizing that "the world is a bloody marvelous place", Thomas Brackenreid feels his life is half over and he's barely scratched its surface. In other words, Brackenreid is having a midlife crisis.
  • Inspector Brackenreid and James Pendrick bonded at the World's Fair in St. Louis and Murdoch feels left out.
  • Before escaping Station House No. 4, The Lurker (aka James Pendrick) gives Dr. Julia Ogden a long swooping kiss, afterwards Julia calmly states, "I've had better."
  • Brackenreid has been grabbed by wanderlust. No longer content being a station house copper, Thomas  goes off on a quest with Pendrick in pursuit of Ashmi, who’s stolen the inventor’s formula for the fountain of youth.


Historical References



  • The first recorded use of the proverb "An apple a day keeps the doctor away" was in the 1860s in Wales, UK. The original wording of the saying was "Eat an apple on going to bed, and you'll keep the doctor from earning his bread." The current phrasing was first used in print in 1922.
