Although "Sherlock" returned for its second season in the UK earlier this year, fans in the United States will have to wait until this Sunday, May 06 to see the modern day update of Sherlock Holmes as a part of PBS' "Masterpiece Mystery."

Created by "Doctor Who" veterans Steven Moffat and Mark Gatiss, "Sherlock" has become an international hit and it has propelled its stars Benedict Cumberbatch and Martin Freeman to greater fame and success; which some have blamed for what will likely be a substantial delay between the second and third seasons.

SPOILERS AHEAD for "Sherlock" Seasons 2 & 3

The second season of "Sherlock" ended with the title character apparently dying in battle with his nemesis, James Moriarty in an adaptation of Arthur Conan Doyle's "The Final Problem." Chronologically, the next story in Holmes' cannon is "The Adventure of the Empty House," in which Holmes returned and revealed to Dr. James Watson how he faked his death. As expected, Gatiss confirmed that "Sherlock" season 3 will open with an adaptation of that story, but with some significant changes.

"There’s certain things about 'The Adventure Of The Empty House' which feel set in stone because that’s how Sherlock comes back," said Gatiss during an interview with the Associated Press. "But at the same time we feel free to invent and to introduce new stuff to it. I always found it a little unlikely that Dr. Watson’s only reaction was to faint for instance – as supposed to possibly a stream of terrible swear words."

Gatiss was less forthcoming about which Sherlock Holmes stories will fill out the other two episodes of season three, but Gatiss indicated that he and Moffat will continue to cherry-pick their personal favorite adventures.

"Everybody has their [favorites]," said Gatiss. "Steven and I have our all-time [favorites], but it's really a question of what will fit into the structure. We're sort of guided by our idea for the overall feel of the next three stories."

"Sherlock" season 3 is expected to film in early 2013.
