With season 3 of 'Sherlock' over, many are wondering what the next season of the show will hold. Below, find season four Sherlock spoilers from executive producer Steven Moffat and the actress who plays Mary on the show, Amanda Abbington.

Abbington and Moffat recently discussed the next season of "Sherlock" with TV Guide. Moffat promised that all cliffhangers from the season finale will be answered.

"We're going to fully account for everything we've done, yes. There will be nothing left dangling," Moffat said.

The executive producer Steven Moffat discussed whether or not Molly and Sherlock's relationship were also discussed during the interview with TV Guide.

"I think she's become quite an important part of the show. One of the difficulties in adapting Sherlock Holmes... [is that] there are no women in Sherlock Holmes, the original stories. You really don't have the female perspective on them. And they're slightly flat when they turn up. And yet, every time we bring a woman into Sherlock, it works hugely well," Moffat said.

Abbington discussed her character and said she expects her to return.

"Yeah, Steven and Mark are sitting down furiously writing story lines. There's no reason why she shouldn't come back. I think she's part of the Sherlock family for the time being. I get that feeling from people who've seen it and watched it. They like that she's another dynamic. Mary's still pregnant with a baby girl. But you never know with Mark and Steven. Like they said that Moriarty was dead and yet at the end he's back," she said.
