Here's a bit of a mystery: sightings of a Sherlock edition of Cluedo - the sleuthing boardgame - on websites ranging from Amazon to Forbidden Planet, followed by its disappearance from the latter site and a statement from a BBC source suggesting it may never become a reality.
"We can't confirm this is going ahead," the source told RadioTimes.com "and you definitely won't be able to pre-order it."
Although "temporarily out of stock" on Amazon, the item is still listed for £29.99, hmm?
What's behind the confusion we may never know, but it would seem a shame if the game didn't materialise - Sherlock and Cluedo seem like such a perfect fit.
Assuming that it does go ahead, though, what might we expect?
One description accompanying the game suggests that everyone's favourite consultant criminal Moriarty will end up as a victim of crime himself.
"Who killed Moriarty?" it asks. "Was it Mrs Hudson, in the Tower of London with the Wrench, or Irene Adler, in 221B, with a Candlestick? You’ll need all your wits about you to find out!"
Now, Sherlock fans will think they already have a pretty good idea who killed Moriarty - after all, we saw Sherlock's nemesis turn the gun on himself and pull the trigger at the end of The Reichenbach Fall, right?
But it wouldn't make for much of a game of Cluedo if you already knew whodunnit - so perhaps reports of Moriarty's death have been greatly exaggerated...
