A federal judge in the US recently ruled that the characters in Sir Arthur Conan Doyle’s Sherlock Holmes stories are now in the public domain. So my next novel, after I finish Do Sheep Dream of Woolly Androids?, will be about a torrid love triangle between Sherlock, Mrs. Hudson and Professor Moriarty. Only Moriarty turns out to have been Count Dracula all along. The Hound of the Baskervilles, who is actually a lovelorn werewolf, will also put in an appearance. It will be called The Sign of the Four Shades of the Red-Headed League. The game’s afoot!
