Gabriel Syme
major
Also known as Syme, Mr. Syme, Comrade Syme, Gabriel
Syme is a poet who revolted into sanity, hating modern lawlessness with a fervor that borders on the fanatical. After witnessing a dynamite outrage, he channels his rage into undercover work, posing as Comrade Syme to penetrate the Central Anarchist Council. His paradoxical position—a defender of order embedded among its enemies—drives the novel's central tension between appearance and conviction.
Lucian Gregory
major
Also known as Gregory, Comrade Gregory, Rosamond Gregory
Gregory is the established poet of Saffron Park, a man of red braids and lyrical thunder who argues that chaos is the artist's only creed. His rivalry with Syme—over poetry, politics, and perhaps his sister Rosamond's attention—sparks the debate that sets the plot in motion. He embodies the romantic allure of destruction that the novel both indulges and interrogates.
Sunday
major
Also known as President Sunday, old Sunday
Sunday presides over the anarchist council with an unsettling combination of abstraction and cruelty, his great bright eyes sometimes going quite blind. His physical enormity and dreamy menace make him less a man than a force—one councillor compares him to an absentminded tiger. He is the mystery at the heart of the council, the figure whose true identity and purpose drive the detectives' investigation.
Dr. Bull
supporting
Also known as Bull
Bull is the optimist of the detective party, a man whose sympathy for Sunday persists even as he fights him like hell. He articulates the strange gaiety he senses in Sunday—a supreme strength shown in levity, like an elephant leaping into the sky. His instinctive affection for the enemy complicates the moral clarity of the undercover operation and hints at deeper conspiracies.
Professor de Worms
supporting
Also known as de Worms, Professor
De Worms presents himself as a helpless old man with leaden feet and shaky hands, yet he inexplicably keeps pace with Syme across London. This contradiction—the paralytic who pursues—makes him one of the most unsettling figures in the council. His disguise raises the question of how many of the anarchists are not what they seem, deepening the novel's labyrinth of false identities.
Inspector Ratcliffe
supporting
Also known as Ratcliffe, the gloomy Ratcliffe
Ratcliffe is the Secretary of the council, a man who admits he looked the part of a conspirator from the first. His gloom contrasts sharply with Bull's optimism, and he speaks of Sunday with a knowledge that borders on dread. As the detectives reunite to confront their enigmatic president, Ratcliffe's strained voice and haunted recollections underscore the psychological toll of their deception.
Gogol
supporting
Also known as Brother Gogol, the hairy Gogol
Gogol sits among the seven masked anarchists as the hairy, foreign-looking Pole, but when Sunday unmasks him his thin red hair and pert London voice betray the detective beneath. He takes his exposure with nonchalance, even pride in his own accent-work, and walks out with a stumble that betrays his assumed ease. His unmasking is the first crack in the Council's theatre, teaching Syme that everyone in this game may be playing a part.
Dr. Renard
supporting
Also known as Renard, Doctor Renard
Dr. Renard travels with the reunited detectives by boat and train, keeping close to his companions and pressing for shared cabs and shared drinks. His optimism and conviviality soften the paranoia of the pursuit, and it is he who drags the exposed Gogol back into the fold with the cry that they are all spies. He embodies the story's strange fellowship of pursuers who cannot tell friend from enemy.
Colonel Ducroix
supporting
Also known as Ducroix, the Colonel
Colonel Ducroix arrives at the flower-strewn dueling ground in solemn morning dress, unlocks the case of twin swords, and politely proposes that the play end at first blood. When Dr. Bull insists on fighting until one man is disabled, the Colonel yields with bewildered good manners, kneeling to place the blades and standing as second. His punctilious civility against the absurd stakes of the duel makes him a quiet emblem of the old world watching the new conspiracy unfold.
The Secretary

Sunday's mysterious and silent secretary.
Marquis de St. Eustache

Also known as the Marquis, Marquis de Saint Eustache
A French aristocrat briefly mentioned as a former anarchist.
Buttons
