The game's afoot once more as the long-suffering Dr. John Watson and a partially decomposed Warlock Holmes (though he's getting better) face off against Moriarty's gang, the Pinkertons, flesh-eating horses, a parliament of imps, boredom, Surrey, a succubus, an overly Canadian aristocrat, a tricycle fight to the death, and the dreaded Pumpcrow. Oh, and a hellhound, one assumes.
