Sherlock New Trailer: Holmes & Watson Are Back With Thrilling Suspense

BBC One's Sherlock is back after taking a break for about 2 years. Bringing back the thrilling experience back this Christmas, Sherlock's 4th season new trailer has been dropped. "The stage is set. The curtain rises. We are ready to begin," says Holmes at the start of the trailer.

Sherlock Holmes (Benedict Cumberbatch) and John Watson (Martin Freeman) are coming back together in the Victorian era getting ready for a war. "Every great cause has martyrs," Holmes says in the 1 minute 31 seconds trailer. "Every war has suicide missions, and make no mistake: this is war."

Once Watson asks, "What made you like this," to which the detective replies, "Oh Watson, nothing made me. I made me!"

BBC One's Sherlock shows the two detectives walking down the dark and foggy crowded 19th-century England streets.

Apart from seeing dozens of guns, a woman screams 'Holmes' adding the suspense to the trailer. The first-look clip which was shown at Comic-Con in July showed Holmes, Watson and 221 Baker's Street landlady Mrs. Hudson arguing about their roles in Watson's books and also on why Watson had to grow a mustache!
