The King's Assassin

The King's Assassin is Benjamin Woolley's nonfiction account of George Villiers, Duke of Buckingham, his intimacy with King James I, and the accusations that followed James's death. Pan Macmillan describes the book as the basis for the TV series Mary & George, and Sky's official page also identifies Mary & George as based on Woolley's book. Pan Macmillan lists the paperback with ISBN 9781509837083.

This is a useful source guide because Mary & George is not a novel-first adaptation. The book gives the historical argument, court context, and political stakes behind the series' sex, ambition, and family strategy. It also helps readers separate documented history from dramatic license.

Read it if the Starz or Sky series made you want the source behind the scandal. Skip it if you want a light royal biography or a scene-by-scene companion to the show.

George Villiers rises from minor gentry to royal favorite, then becomes the center of suspicion after James I dies.

King James I is the monarch whose favor, desire, and vulnerability shape the court around him.

Mary Villiers is crucial to the family ascent and to the series' dramatic focus.

The Jacobean court is the wider machine of patronage, rivalry, religion, and accusation.

No. 1 - Direct screen-source value. The book is named by Pan Macmillan and Sky as the source behind Mary & George.

No. 2 - Strong history fit. It gives readers court politics rather than only costume-drama atmosphere.

No. 3 - Clear reader decision. It is best for viewers who want context and argument, not just more scandal.

Read this if you are...

• Coming from Starz or Sky's Mary & George.
• Interested in Stuart court politics, royal favorites, and political rumor.
• Looking for a nonfiction source rather than a novelization.
• Comfortable with history that weighs claims and uncertainty.

Skip it if you are...

• Wanting a simple guilty-or-innocent verdict.
• Looking for a romance novel version of the series.
• Avoiding court intrigue, sexual politics, or historical homophobia.
• Uninterested in seventeenth-century English politics.

• Keep allegation and proof separate. The book's power comes from the gap between rumor, evidence, and political usefulness.
• Track patronage. Court favor is not background. It is the system.
• Notice Mary's role. The show foregrounds her, and the book helps explain why the family strategy mattered.
• Expect the series to compress. Television turns history into scenes; the book gives the slower argument.

• Hilary Mantel - Wolf Hall. External comparison for Tudor and Stuart power rendered through court proximity.
• Robert Graves - I, Claudius. External comparison for intimacy, suspicion, and succession politics.
• James Clavell - Shogun. For political survival inside a courtly power system.
• Julian Barnes - Arthur & George. For British history shaped through investigation and reputation.
• Philippa Gregory - The White Queen. For readers who want more monarchy, ambition, and family strategy in fiction.
