My absolute favorite author, Neil Gaiman, has written (and published) SHERLOCK HOLMES FANFICTION. :D It’s called A Study in Emerald and it’s included in his (fantastic) short story collection, Fragile Things. I tend to pick and choose when it comes to anthologies - I sort of skip around and don’t start at the beginning and sometimes what happens is I forget to read a couple of the stories. And somehow I forgot to read this one until today, although I’ve owned the anthology for 3 years, what the actual hell.
Point being: The story is brilliant on so many levels, like everything Neil Gaiman writes. I mean, come on, he’s the man who brought us American Gods, Neverwhere, Anansi Boys, Coraline, Stardust, et al, what did I expect? But still - I was absolutely blown away.
And - lucky you! - he’s put it online in a stylish lovely newspaper-print format for all to read.
ENJOY. You will. I promise.
