The Improbable Adventures of Sherlock Holmes

Twenty eight stories written over a span of twenty two years, these tales feature Holmes and Watson and something outside the norm, from ghosts to Cthulhu to physics and time travel. A really excellent collection from some very big-name authors.

Hard to pick favorites from this collection, but the offerings of Neil Gaiman and Anthony Burgess are both excellent.

The audio book version of this collection contains only twenty seven stories, lacking Stephen King's "The Doctor's Case", which was also published in his Nightmares and Dreamscapes and, I understand, performed in audio by the inestimable Tim Curry.
