Beyond Baker Street lies a vast world wrapped in darkness, a shadow realm that does not defy logic as much as challenge it. When eldritch terrors impinge upon the domain of humanity, Sherlock Holmes does not turn away, does not flee in horror. Instead, he does what he has always done...defend civilization with his keen intellect and unassailable logic. In these stories, he encounters foes unlike any other he has ever faced, from a ravenous creature lurking beneath Whitechapel to a nameless terror of the elder woods in legend-haunted Hammershire County. The collection includes "The Adventure of the Ancient Gods," first-ever story set in the universes of Sherlock Holmes and HP Lovecraft, as well as "The Terror Out of Time," first story to bring Professor Challenger and Sherlock Holmes in a Lovecraft-inspired tale.
