The UK sensation Sherlock has arrived in the U.S., airing as a part of the PBS series Masterpiece Mystery, and series co-creators Mark Gatiss and Steven Moffatt are hoping that it will strike a chord with American viewers.

Gatiss and Moffatt are best-known for the international hit Doctor Who and are self-professed "Holmes" geeks since childhood. Sherlock places the iconic characters of Sherlock Holmes and Dr. John Watson in current-day London for a contemporary telling of their mis-adventures.

An exceptional cast is led by Benedict Cumberbatch as Sherlock Holmes and Martin Freeman as Dr. John Watson. Martin Freeman hopes the American audience will react as favorably as the British audience to the modern adaptation.

"It was some of the best writing I had probably ever read for television, series star Martin Freeman said. I hope that Americans go with it, because the most important thing about the Sherlock Holmes stories isn't the frock coat. It's the essence of what he is, and the essence of what the [Holmes and Watson] relationship is. And chasing bad guys."

During its debut run in the UK, Sherlock's three 90-minute episodes averaged 7.2 million viewers earning the show a pick-up for a second season to air in 2011.

"We've been overwhelmed by the warmth of response to our new Sherlock Holmes and John Watson and can't wait to take them on three new adventures next year, Gatiss and Moffatt said, regarding the second season pick-up. There'll be baffling new puzzles, old friends and new enemies. And we might well be seeing the cold master of logic and reason unexpectedly falling.

Some hints Moffatt revealed about the second season were the words, "Adler, Hound, Reichenbach." Those words are all references to original stories about Sherlock Holmes. Irene Adler is a character from the short story A Scandal in Bohemia, and is considered a love interest for Holmes; The Hound of the Baskervilles was one of the four Sherlock Holmes novels written by Arthur Conan Doyle; and Reichenbach is the location where Holmes and his archenemy, Moriarty, have their final battle.

Sherlock airs Sundays at 9 p.m. ET as part of PBS' Masterpiece Mystery.
