From a media release:

Shaftesbury announced today that production has begun on Macy Murdoch (8×11), a new tween series from CBC Gem that follows the adventures of Detective William Murdoch’s time-traveling great-great-great-granddaughter. The series is a spin-off from Shaftesbury and CBC’s long-running hit drama Murdoch Mysteries, based on novels by Maureen Jennings. The series is currently filming in Toronto and will debut on CBC Gem in Spring 2023.

Sixteen-year-old Macy is a forensic prodigy who, with the help of her two friends, Zane and Billie, uncovers a centuries-old mystery. When a villain uses a time machine to frame the famous Edwardian-era detective William Murdoch for murder, Macy and her friends travel back in time to find the true culprit of the crime. Not only do the teens try to solve a difficult case, but the trio go undercover trying to solve a mystery set in 1910 without the help of modern technology.

Macy Murdoch captures the playful, mysterious spirit of Murdoch Mysteries with Canadian Film Award winner Shailyn Pierre-Dixon (Pretty Hard Cases, The Book of Negroes), who co-directs the series with Beau Han Bridge, who plays Zane, and Raffa Virago billy The series will have a special guest appearance by Spencer West, while Shanice Banton (“Mrs. Violet Hart”) and Lachlan Murdoch (“Constable Henry Higgins-Newsome”) from the hit CBC series will appear as guides on the series to young detectives help clear Murdoch of a crime he did not commit.
