London, 1885. In a city of fog and darkness, the notorious thief Edward Shade exists only as a ghost, a fabled con, a thief of other men's futures -- a man of smoke. William Pinkerton is already famous, the son of a brutal detective, when he descends into the underworld of Victorian London in pursuit of a new lead. His father died without ever tracing Shade; William, still reeling from his loss, is determined to drag the thief out of the shadows. Adam Foole is a gentleman without a past, haunted by a love affair ten years gone. When he receives a letter from his lost beloved, he returns to London in search of her; what he learns of her fate, and its connection to the man known as Shade, will force him to confront a grief he thought long-buried. What follows is a fog-enshrouded hunt through sewers, opium dens, drawing rooms, and seance halls. Above all, it 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.
