From a media release:

Shaftesbury and CBC announced today that award-winning, Canadian actor Paul Sun-Hyung Lee (Kim’s Convenience, Avatar: The Last Airbender, The Mandalorian) will join the cast of the CBC original hit series MURDOCH MYSTERIES as the series commences production on its 18^th season in Toronto. Lee enters the “Murdoch-verse” as Inspector Albert Choi, who brings a whole new perspective to Station House #4. Best known for his portrayal as Appa on Kim’s Convenience, as well as Uncle Iroh on Netflix’s live-action remake of Avatar: The Last Airbender, this new role marks Lee’s first foray into the world of period drama. 

CBC’s most-watched show and Canada’s top-rated long-running drama, MURDOCH MYSTERIES is set in Toronto in the early 1900s during the age of invention, where Detective William Murdoch (Yannick Bisson) enlists innovative forensic techniques to solve some of the city’s most perplexing murders. Notable guest stars on the series have included William Shatner, Margaret Atwood, Geddy Lee, Chris Hadfield, Ed Asner and Nick Nurse, adding star-studded intrigue to its compelling tales. The 18^th season, consisting of 22 episodes and celebrating the series’ 300^th episode, will broadcast on CBC and CBC Gem in Canada this fall, Acorn TV and Ovation TV in the U.S. and on Alibi in the UK.

Ahead of the Season 18 premiere of MURDOCH MYSTERIES this fall, a special ‘Beginner’s Guide to Murdoch Mysteries’ collection is now available to stream for free on CBC Gem. The 10 iconic episodes are the perfect Murdoch primer pulled from across the series and highlight the show’s trademark mystery, murder and Detective Murdoch’s unflappable resolve. 

“We are delighted that Paul has joined us in the world of Murdoch,” says Executive Producer Peter Mitchell. “Paul brings a wealth of experience to his role as Inspector Albert Choi and we think the fans will really enjoy seeing him on the team at Station House 4.”

Season 18 is full of ‘Murdochian’ delights: a murder at a Charles Dickens convention; Murdoch acting as a bodyguard for a silent film star (Siobhan Murphy) and thrown into a cinematic adventure himself; foiling a theft of the world’s largest ruby; proving the veracity of a ‘Missing Link’ skull found in Milton, Ontario; and a holiday episode celebrating the ‘misfits’ and singletons.  Episodes that root mysteries in the social issues of the time are also explored: a worker’s strike at a factory; an early instance of low-income housing; competing public hydro projects; and immigrants trying to purchase land in the ‘paradise’ of the wilds of Canada. 

MURDOCH MYSTERIES was born out Maureen Jennings’ 1997 novel Except the Dying. Key characters in Murdoch’s world include Chief Constable Thomas Brackenreid (Thomas Craig), Constables George Crabtree (Jonny Harris) and Henry Higgins (Lachlan Murdoch), Detective Llewellyn Watts (Daniel Maslany), Chief Coroner Violet Hart (Shanice Banton), Margaret Brackenreid (Arwen Humphreys) and Effie Newsome-Crabtree (Clare McConnell) as Canada’s first female Crown Attorney. In addition, the milestone 300^th episode will see Detective Murdoch visit the UK to see his wife, Dr. Julia Ogden (Hélène Joy), as they celebrate their wedding anniversary. This season will also introduce several fresh, new faces, as well as combining the history, humour, romance, and adventure that makes MURDOCH MYSTERIES so popular and unique for viewers around the world. 

MURDOCH MYSTERIES is developed and produced by Shaftesbury, in association with CBC, ITV Studios, and UKTV, and with the participation of the Canada Media Fund, the IPF’s COGECO Television Production Fund, the Canadian Film or Video Production Tax Credit and Ontario Creates. Shaftesbury Sales Company and ITV Studios hold worldwide distribution rights for the series.
