Toby Jones Character in Sherlock is the Darkest One Ever Written: Steven Moffatt

London: Steven Moffatt thinks new Sherlock villain Toby Jones is "unnerving".

The showrunner thinks the 50-year-old actor's Culverton Smith is the "darkest villain ever written" for the show and thinks fans will enjoy his appearance in the upcoming festive episodes of the popular drama, which stars Benedict Cumberbatch as the titular detective, reported Femalefirst.

"He's very unnerving. I hope Toby won't mind me saying, but he's a little man, yet he's weirdly a physical threat. He exudes an enormous amount of menace," Moffatt said.
