Perhaps it’s not a mystery evocative of eerie moors or Victorian London alleyways, but the question still perplexes me: how did I let writer Martin Powell escape from my radar screen?

He’s certainly on the radar screen of other Sherlock Holmes fans. His adaptation of “The Hound of The Baskervilles” has just been released as a full-color hardcover graphic novel from Sequential Pulp/Dark Horse Comics. (The book is available in comic book specialty shops, as well as through Amazon, Barnes and Noble, Books-A-Million and other purveyors of fine literature.)
