Samantha Bond, who we know as Lady Rosamund on the popular British period drama, will be the guest-of-honor star. Bond will join guest actors including Peter Keleghan, Peter Stebbings, Alex Paxton-Beesley, Daniel Maslany and Bea Santos in Season 10 of Murdoch, which has started filming in Ontario since May 24, The Star reveals.

“The series returns with debutantes vying for the hand of Toronto’s most eligible bachelor — think The Bachelor in 1904! — and there is a killer on the loose,” executive producer Christina Jennings communicated during a news release. “At the same time, Toronto is thrown into chaos by the Great Fire. It will be a great launch to a great season.”
