“If your man is more dangerous than the late Professor Moriarty, or than the living Colonel Sebastian Moran, then he is indeed worth meeting. May I ask his name?”
— Sherlock Holmes
Before one reads John Linwood Grant’s A Study in Gray (18thWall, 2016), one might want to read Arthur Conan Doyle’s “The Illustrious Client” (1924). It’s among the last of Doyle’s Sherlock Holmes tales, the one from which my epigraph comes. Grant continues Doyle’s story in A Study in Gray, using that earlier, loosely resolved case to pull the great detective out of apiarian retirement and into Grant’s own world of supernatural espionage. This more occult realm of intrigue — along with its lead characters: Captain Redvers Blake, Abigail Jessop, and Henry Dodson — exist in Grant’s The Last Edwardian series.
