What was the title of Sherlock’s 2013 online mini-episode?

Sherlock’s 2013 online mini-episode was titled “Many Happy Returns.”

The seven-minute mini-episode was released during the 2013 Christmas period as a prequel to Sherlock’s third series. It was made available through BBC iPlayer, the BBC Red Button service and the BBC’s YouTube channel, rather than being a standard full-length television episode.

The story takes place after Sherlock’s apparent death at the end of “The Reichenbach Fall.” Anderson, the former forensic technician, has become obsessed with proving that Sherlock is still alive. He presents Lestrade with a series of incidents around the world that appear to show Sherlock secretly continuing to investigate crimes.

“Many Happy Returns” helps bridge the two-year gap before series three and prepares viewers for Sherlock’s return. It is often confused with “The Empty Hearse,” the first regular episode of series three, which follows the mini-episode and explains more of Sherlock’s survival.
