After taking a week off for the Halloween season, a change is introduced to the scheduling of Canadian TV drama series "Murdoch Mysteries" at CBC. Episode 6 titled "The Accident" which was originally scheduled to air on Monday, Nov. 6, has been moved to the following Monday, Nov. 13. Taking its place in this week's slot is "21 Murdoch Street." 

The synopsis for "21 Murdoch Street" reveals that Constable George Crabtree (Jonny Harris) and Constable John Brackenreid (Charles Vandervaart) will be going undercover to look into a murder in a prestigious boys' school. The duo will also be looking to break up a gambling ring inside campus.

This suggests that both Crabtree and Brackenreid will be in school uniforms to investigate on the gambling ring and the murder inside the boys' school. Crabtree will likely make use of the case to make an impression on the students in campus with a certain published novel.

Meanwhile, "21 Murdoch Street" is anticipated to continue the build up on the character of Dr. Julia Ogden (Hélène Joy). The episode is expected to delve into Julia's journey in advancing the science behind infertility. It is also presumed to contain a brief romantic moment between Julia and Detective William Murdoch (Yannick Bisson).

Additionally, the awaited return of Detective Llewelyn Watts (Daniel Maslany) is banked on to come in "21 Murdoch Street." Watts was initially introduced in the 10th season, and like Brackenreid, has lots of catchphrases like Hellfire, Sweet Mary, and Crackerjack. His last appearance was in the first episode of the 11th season.

"The Accident" will air on Monday, Nov. 13. The anticipation for the episode will extend for another seven days. Showrunner Peter Mitchell has not made a statement regarding the switch of episodes.

"Murdoch Mysteries" season 11 airs Mondays at 8 p.m. NT on CBC in Canada.
