Acorn TV Releases New 'Murdoch Mysteries' Season 18 Trailer

Murdoch Mysteries’ eighteen seasons may seem paltry next to shows like the U.K.’s Midsomer Murders (Season 25) or Silent Witness (Season 28). However, on this side of the pond, it’s nearly legendary as Canada’s longest-running scripted one-hour drama series. The period mystery series first debuted in 2008, the same year Hulu debuted in the U.S., and three years before Downton Abbey and Game of Thrones changed the TV landscape. Set in Toronto in the early 1900s during the age of invention, it follows the case of Detective William Murdoch, played by Yannick Bisson (Casino Jack).

The series is also notable in debuting with four principal characters: Bisson as Murdoch, Thomas Craig as Inspector Thomas Brackenreid,  Jonny Harris as Constable George Crabtree, and Hélène Joy as Dr. Julia Ogden. Until this year, with Season 18, all four appeared in almost every episode. (Joy’s character is now in the U.K. and will only appear in a few select installments.) However, the series used that to its advantage, finally casting the show’s first-ever actor of color, Paul Sun-Hyung Lee (Kim’s Convenience), as Inspector Albert Choi, who “brings a whole new perspective to Station House #4.”

The new season has 22 installments, including the series’ record-breaking 300th episode. (It falls on Season 18’s tenth episode, for those keeping track.) Though the series has been airing and streaming Season 18 for free on the CBC and the little-watched U.S. network Ovation since October 2024, its arrival on Acorn TV signals the season's transition to its regularly scheduled streaming platform.
