A Study in Brimstone — G.S. Denning

Meet Holmes -- Warlock Holmes, that is -- in this laugh-out-loud mash-up that puts a paranormal spin on 6 classic Sherlock Holmes stories!

Ogres and vampires, “Holmesian callbacks,” and “Douglas Adams-worthy puns” -- a “charming and well-imagined” ode to the Great Detective (Barnes & Noble SFF Blog).

Sherlock Holmes is an unparalleled genius. Warlock Holmes is an idiot. Warlock Holmes is a font of arcane power -- but he's brilliantly dim. Frankly, he couldn't deduce his way out of a paper bag.
 
The only thing he has going for him are the might of a thousand demons and his stalwart companion. Thankfully, Dr. Watson is always there to aid him through the treacherous shoals of Victorian propriety -- and save him from a gruesome death every now and again.
