The Man Who was Thursday (Annotated) characters

By G. K. Chesterton

Every entry below is hidden until you open it, and each names the chapter the character first appears in.

Gabriel Syme (Protagonist)

Appears from the start

A poet committed to order who argues that genuine art depends on rules rather than chaos. His polished appearance conceals work as a detective assigned to infiltrate the anarchist movement. He is courageous and imaginative, but his habit of interpreting danger through symbols makes his investigation increasingly strange.

Lucian Gregory (Antagonist)

Appears from the start

A poet of revolt living in Saffron Park and Rosamond's brother. He treats anarchy as a serious political commitment and resents Syme for dismissing it as an artistic pose. Their public debate leads him to offer proof that his beliefs are more than talk.

Rosamond Gregory (Supporting)

Appears from the start

Lucian Gregory's sister, whose observation about the poetry of an ordinary railway timetable begins the argument between Gregory and Syme. Syme is immediately drawn to her quiet intelligence and to the settled domestic world she represents.

The Policeman (Supporting)

Also known as The Philosophical Policeman

First appears in chapter 2

A senior official in a special police unit devoted to combating intellectual anarchism. He recruits Syme after recognizing that the poet's defense of order is sincere, and he frames police work as a struggle of ideas as much as a hunt for criminals.

President Sunday (Antagonist)

Also known as The President, Sunday

First appears in chapter 4

The immense and unnervingly agile president of the anarchist Central Council. Known by the weekday assigned to his office, he dominates his fellow conspirators through humor, threats, and an apparent ability to anticipate every secret. Syme regards him as the controlling enemy behind the council.

Gogol (Minor)

Also known as Tuesday

First appears in chapter 4

A council member presented as a wild-haired Polish anarchist. His theatrical manner and repeated demands for immediate violence seem extreme even among his companions at the first meeting Syme attends.

The Marquis de Saint Eustache (Antagonist)

Also known as Wednesday

First appears in chapter 4

A polished French nobleman occupying Wednesday's place on the anarchist council. Elegant, composed, and reportedly deadly in a duel, he is assigned a central role in the council's plan to attack an international political gathering in Paris.

Professor de Worms (Antagonist)

Also known as Friday

First appears in chapter 4

An apparently ancient German scholar on the anarchist council, bent by age and speaking with slow authority. He is associated with the movement's intellectual and scientific side, and his uncanny attention makes Syme fear that his police identity has been recognized.

Dr Bull (Antagonist)

Also known as Saturday

First appears in chapter 4

A young council member whose dark spectacles make his expression unreadable. He appears physically formidable and fanatically committed to the conspiracy, and Syme initially regards him as one of the most dangerous men at the table.

The Secretary (Antagonist)

Also known as Monday, Ratcliffe

First appears in chapter 4

The council's grave secretary and holder of Monday's seat. His bleak appearance and efficient obedience to Sunday make him seem the most administrative of the conspirators and leave Syme uncertain how much he knows about the president's plans.
