The criminal activities of Mayor Vaughn and the aftermath of Petrucci’s confession are expected to drive the investigative arc.

Quick Season 18 Recap

Just in case you don’t quite remember how season 18 played out, and more importantly, how it ended on that cliffhanger, here’s a quick recap to get back up to date.

Season 18 plunged Murdoch and his team into some of their most challenging cases yet. The detectives faced an immigrant-targeting land scam, the murder of an archduke linked to a political conspiracy, and a serial killer terrorizing men of multiple cultures.

Notably, the team celebrated numerous milestones, including William and Julia’s anniversary in London during the landmark 300th episode.

Throughout the season, themes of corruption, ambition, and justice persisted, and in the explosive finale, Murdoch ended a hydroelectric financial scandal by unraveling gangster Tony Petrucci’s web of crime, only for Mayor Chadwick Vaughn to abruptly fire Station House 4’s staff.

Julia Ogden’s presence was reduced, appearing briefly, leaving viewers uncertain about her future with William.

New characters, shifting alliances, and unresolved emotional arcs set the stage for major changes ahead, and hopefully, all of them will be resolved in season 19!

Will Julia Ogden Be In Season 19?

Dr. Julia Ogden, played by Hélène Joy, has had a tumultuous journey through the series.

In earlier years, Julia left the morgue to pursue work in Buffalo and later Toronto, navigating marriage, medical practice, and social activism, but recently her appearances became sporadic.

During Season 18, Julia appeared in only two episodes, leaving her relationship with Murdoch unresolved and her character’s future ambiguous.

However, great news for fans – Hélène Joy is confirmed to return for Season 19, resuming her role as Julia and addressing these dangling storylines.

We can expect new developments in Julia’s professional and personal life as the show finds space for her story amid the shifting cast dynamics.

Who Plays Who?

Detective William Murdoch (Yannick Bisson): The inventive, principled detective at the heart of the show.

Dr. Julia Ogden (Hélène Joy): Murdoch’s wife, a pioneering physician and social reformer.

Inspector Thomas Brackenreid (Thomas Craig): Murdoch’s gruff, loyal superior.

Constable George Crabtree (Jonny Harris): Murdoch’s enthusiastic assistant and aspiring writer.

Inspector Albert Choi (Paul Sun-Hyung Lee): New lead inspector introduced in recent seasons.

Effie Newsome-Crabtree (Clare McConnell): George Crabtree’s wife, adding to the show’s comic and emotional beats.

Chief Coroner Violet Hart (Shanice Banton): The driven medical examiner whose expertise and ambition often shape investigations.

Henry Higgins (Lachlan Murdoch) and Detective Llewellyn Watts (Daniel Maslany): Eccentric members of Murdoch’s team, contributing both humour and depth.

Margaret Brackenreid (Arwen Humphreys): Thomas’s wife, who provides plenty of fun and drama.
