A deeply atmospheric literary tour de force with a cast of unforgettable characters, By Gaslight is the remarkable story of one detective’s ceaseless hunt for an elusive criminal.

London, 1885. A woman’s body is discovered on Edgware Road; ten miles away, her head is dredged from the dark, muddy waters of the Thames. Famed detective William Pinkerton had one lead to the notorious thief Edward Shade, and now that lead is dead. Determined to drag Shade out of the shadows, Pinkerton descends into the seedy underworld of Victorian London, with its gas-lit streets, opium dens, sewers and seance halls, its underworld of spies, blackmailers, cultists, petty thieves and pitiless murderers.

Adam Foole is a gentleman without a past, haunted by a love affair ten years gone. Returning to London in search of his lost beloved, his journey brings him face-to-face with Pinkerton, and what he learns of his lover’s fate will force him to confront a past - and a grief - he thought long buried.

Epic in scope, brilliantly conceived and vividly atmospheric, By Gaslight is a riveting portrait of two men on the brink. Shrouded in secrets, betrayals and deceptions, this is the story of the most unlikely of bonds: between William Pinkerton, the greatest detective of his age, and Adam Foole, the one man who may hold the key to finding Edward Shade.
