Warlock Holmes is dealing with a jerk, who just so happens to be a stockbroker. There may be a link. He's also trying to hunt down some tokens to control something magical (it's all rather complicated), and Moriarty just won't stop taking over people's bodies.

'If you ever wondered how much better Sherlock would be if people could hurl hellfire at each other, well this one is for you.' — Starburst Magazine on Warlock Holmes: A Study in Brimstone
'Damn you, G.S. Denning! Damn you, sir, for tainting the Great Detective with your parodic fripperies and your supernatural folderols! There is a special place in Holmesian hell reserved for impudent whelps such as yourself - and I shall languish there alongside you for the sin of having read your book and laughed like a loon throughout.' — James Lovegrove, New York Times bestselling author of The Age of Odin
