Downton Abbey co-creator Gareth Neame has suggested the show’s character Lady Mary Crawley could be a femme fatale when it comes to lovers.

The character, played by Michelle Dockery, had a night of passion with a Turkish diplomat who died in bed, and then in the last series her husband Matthew, played by Dan Stevens, died in a car crash.

Gareth told the Daily Star: “I do wonder if there is a praying mantis situation occurring. They get to do it once, then she kills them.”

In the coming series Lady Mary will have a flirty romance with Lord Gillingham, played by Tom Cullen.

Lady Mary’s sister Edith (Laura Carmichael) will continue her affair with married editor Michael Gregson (Charles Edwards).

Widower Tom Branson (Allen Leech) will get a new love interest too, in the form of a governess played by Daisy Lewis.

Gareth recently said Downton Abbey had a long time left to run, but would finish before it got to World War II.

“The show is so popular around the world now… It’s beloved,” he said. “The fourth season is in extremely good health, and my mind is already in the fifth season. I will say we’re not going to World War II, but that’s 18 years away. We want to make the show. When we feel it’s had its time, hopefully we’ll know before you guys. But it’s not anytime soon.”
