Each volume is introduced by a short essay from a Holmes scholar or contemporary mystery novelist, providing excellent context for the story, its original production, and the way it was initially received. I've loved Sherlock Holmes all my life, and I've read the original novels a dozen times or more, but these adaptations still brought new life and energy to the familiar texts. But they're not just a great complement for a Holmes-lover's collection -- they'd make an excellent introduction to the original stories, for adults and sharp adolescents alike.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
