Setting

The main setting is a universe dominated by the Magisterium, an international theocracy that actively suppresses heresy. In Lyra's world, human souls exist outside their bodies as sentient dæmons in animal form. The alethiometer, a truth-telling symbol reader, serves as an important plot device. The Subtle Knife, called Æsahættr, can cut windows between worlds.

Plot

Twelve-year-old Will Parry lives in Oxford caring for his mother, who has mental health problems. After accidentally killing an intruder, he flees and stumbles on a window to another world, entering the city of Cittàgazze where he meets Lyra and her dæmon Pantalaimon. Mrs Coulter tortures a witch for a prophecy about Lyra, but the witch is killed by Serafina Pekkala before revealing details. The aeronaut Lee Scoresby searches for Stanislaus Grumman, rumored to have knowledge of a powerful object.

Will returns to his world seeking information about his missing father; Lyra accompanies him to learn about Dust. On her alethiometer's advice, Lyra visits physicist Dr Mary Malone, whose computer communicates with dark matter. Lyra realizes dark matter corresponds to Dust. After accepting a lift from Sir Charles Latrom, Lyra discovers he has stolen her alethiometer; he offers to return it for a powerful knife in Cittàgazze.

Will defeats a youth who took the knife from Giacomo Paradisi, losing two fingers. Paradisi explains this signifies Will as the new bearer, and the knife can cut through any material, even between worlds. Will and Lyra learn Cittàgazze is haunted by soul-eating spectres that prey on adolescents and adults. Will uses the knife to cut into Sir Charles's home, overhearing a conversation with Mrs Coulter.

Lyra realizes Sir Charles is Lord Boreal from her world; Will hears news of his father, who disappeared after discovering a window between worlds. They escape to Cittàgazze with the alethiometer and are rescued by Serafina Pekkala, who unsuccessfully tries to heal Will's hand.

Adaptations

The film adaptation of The Golden Compass earned more than double its production costs globally but underperformed in the United States, which put plans for a movie version of The Subtle Knife on hold. Producer Deborah Forte remained determined to complete the trilogy, stating she believed enough people saw it as a viable franchise. However, Philip Pullman confirmed in 2011 that no sequels would follow due to the first film's weak US box office. An audiobook with a full cast and narration by Pullman came out in 2000.

BBC Radio 4 broadcast a radio drama featuring Terence Stamp and Lulu Popplewell. London's Royal National Theatre staged a two-part, six-hour performance from December 2003 to March 2004, with a second run from November 2004 to April 2005, starring Anna Maxwell Martin, Dominic Cooper, Timothy Dalton, and Patricia Hodge. The BBC-HBO television adaptation, approved in September 2018, covers The Subtle Knife in its second series, with key characters introduced in the first.
