A first-person narrator recounts how a drunken wager forces him into manual work and a new employment that quickly entangles him in mystery. He learns unsettling news, uncovers a network of conspiracies, and is accused of murder, prompting him to investigate, question acquaintances, and follow leads. Gradually he confronts a shadowy authority figure called the Black King, pieces together motives and deceptions, weathers betrayals and surprises, and pushes toward a final confrontation that resolves hidden loyalties and brings the central mysteries to light.
