"(Stephen King is very good at writing Holmes and Watson.)"
Oh, I had no idea!

He really captures the characters' voices!. His Holmes and Watson are smart and care about each other. The mystery is very good too. The story is called 'The Doctor's Case' originally published in "The New Adventures of Sherlock Holmes". Wikipedia told me that it was adapted into a short film.

"A Study in Steampunk: Choice by Gaslight"
It's an eye-catching title. :)
