LORD JOHN AND THE HAND OF DEVILS is not a novel, but rather a collection of three novellas:

 In Lord John and the Hellfire Club, Lord John glimpses a stranger in the doorway of a gentlemen's club—and is stirred by a desperate entreaty to meet in private. The rendezvous forestalled by a sudden murder, Lord John will wade into a maze of political treachery and a dangerous, debauched underground society. . . .

In Lord John and the Succubus, English soldiers fighting in Prussia are rattled by the nocturnal visitations of a deadly woman who sucks life and soul from a man. Called to investigate the night-hag, Lord John finds a murdered soldier and a treacherous Gypsy, and comes to the stark realization that among the spirits that haunt men, none frighten more than the specters conjured by the heart. . . .

In Lord John and the Haunted Soldier, Lord John is thrust into the deadly case of an exploding battlefield cannon. Wounded in the same battle, Lord John is called to tesify and soon confronts his own ghost—and the shattering prospect that a traitor is among the ranks of His Majesty's armed forces.
