When season 9 of CBC's "Murdoch Mysteries" returns on Monday, viewers will see George Crabtree still behind bars for the murder of his sweetheart's abusive husband, Archie Brooks.

The premiere episode is titled "Nolo Contendere" and Murdoch is committed to getting his assistant out of prison. For that he looks into another inmate's stabbing that could be connected to this case.

Season 9 will pick up five months after the events of season 8 finale that not only saw George behind bars, but it also featured another cliffhanger when Lillian asked Emily to move to London.

Previewing what's in store for the upcoming season, showrunner Peter Mitchell told Tv-eh.com that there's more than what meets the eye when it comes to Archie's murder.

"It's Murdoch, of course there's more to this story than meets the eye. Probably more than even George is aware of. It goes deeper than what George thinks is going on," the showrunner said.

"It will pick up about five months later and George will be in completely different circumstances. Our fans are pretty diligent about changing seasons, we can never pick up right where we left off. We end a season with snow on the ground and we'll pick up, hopefully, with leaves on the trees," Mitchell said.

Elaborating on season 9, Mitchell also noted that fans will get to see more of William and Julia's relationship. As fans of the mystery drama know, the duo finally got married in the previous season of the show after a series of breakups and reconciliations.

"Never having them get together was never an option. We've been promising the audience pretty much from the get-go that these two belong together and you simply can't end the series without them ultimately being together," co-executive producer and writer Paul Aitken was quoted as saying by the media outlet.
