Gaiman's Cthulu/Sherlock mashup "Study in Emerald" -- free audio

HarperCollins has released a free MP3 of Neil Gaiman reading his Hugo- and Locus-winning story "A Study in Emerald," which mashes up Sherlock Holmes and Lovecraft's Cthulhu mythos -- a story that transcends mere gimmick and is poignant, and engrossing. I first heard Gaiman's reading of the story in the audiobook edition of Gaiman's excellent collection Fragile Things and had to pull over to give it my full concentration. Gaiman's a great reader and an even better writer. Link, MP3 Link (Thanks, Chris!)
