The Murdoch Mysteries has just started filming its 14th series. And this time Yannick Bisson not only plays Detective William Murdoch, but also occasionally takes on the role of director. The show's as much a costume drama as a whodunnit. Set in Toronto, it began in the last years of the 19th century and has now moved into the early part of the 20th century. Lynn Freeman talked with Yannick Bisson shortly after he got the first two episodes of series 14 in the can.
