The List of Seven
By Mark Frost
Young Arthur Conan Doyle battles the wicked forces of the Dark Brotherhood to defend the Crown. He is aided by Queen Victoria's best agent, Jack Sparks, a man of keen wit who bears a great resemblance to Doyle's later creation, Sherlock Holmes. Demons, zombies, and the Dweller on the Threshold make this a more pungently purple mystery than many in Victoriana.
From the co-creator of the television series, Twin Peaks. The story is continued in The Six Messiahs.
