How could I pass by Sherlock at Christmas? The Case of the Disappearing Beaune opens with Watson stopping by Sherlock's rooms to invite him to Christmas dinner. Sherlock, of course, refuses, but as he gives Watson his Christmas gift, a bottle of beaune, the pair realizes the wine has been replaced with sand. And Sherlock knows where that sand is from. Sherlock is sure it signifies a threat to the king, so off the two go, on a race through London to solve the case.
For a short story, there were several twists and it showed off Holmes' detecting style well. We also encounter several old friends along the way.
It's a sweet, light Christmas story with a rather surprising ending. It makes a perfect holiday story, but perhaps a slightly disappointing mystery.
