A young Arthur Conan Doyle confronts an occult conspiracy in “a ripping good tale” by the New York Times–bestselling author and co-creator of Twin Peaks (The Washington Post Book World).

As the city of London slumbers, there are those in its midst who conspire to rule the world through the darkest and most nefarious means. These seven, seated in positions of extraordinary power and influence, marshal forces from the far side to aid them in their fiendish endeavor.

In the aftermath of a bloody séance and a terrifying supernatural contact, a courageous young doctor named Arthur Conan Doyle finds himself drawn into a malevolent conspiracy beyond human comprehension, and into the company of a mysterious genius named Jack Sparks.

The future is not safe, as a thousand-year reign of pure evil is about to begin—unless a small group of stalwart champions can unravel the unspeakable mysteries behind a crime far more terrible than murder . . .

“Exhilarating . . . Sparks and Doyle race from one cliffhanger to the next, mixing it up with zombies, villains, giant leeches, and femmes fatales; exploring secret tunnels and a walled castle; crossing paths with Bram Stoker, Madame Blavatsky, Jack the Ripper, and Victoria Regina.” —Kirkus Reviews

“Scary and compulsive, with a chilling twist.” —Vogue

“A knockout . . . engrossing, strange and terrifying.” —Booklist

“Plenty of detail and fast-paced action.” —The Denver Post

“Compelling . . . bizarre . . . will linger long in the reader’s memory.” —San Francisco Chronicle
