"An Unconventional Holmes"

Sherlock Holmes must solve three cases that carry him into the unnatural: the disappearance of the Baker Street Irregulars, the true identity of a Great War veteran, and a vampyre’s grisly death. When he crosses into the worlds of the Grimm Brothers and Bram Stoker to unravel the mysteries confronting him, he will learn whether his conventional methods still function in the unconventional world.
