Lyra's Oxford is a short book by Philip Pullman depicting an episode involving the heroine of His Dark Materials, Pullman's best-selling trilogy. Lyra's Oxford is set when Lyra Belacqua is 15, two years after the end of the trilogy. The book consists mainly of an illustrated short story, "Lyra and the Birds". A fold-out map of "Oxford by Train, River and Zeppelin" is bound in the book, a fictional map of the Oxford that exists in Lyra's world. It also includes some advertisements for books and travellers' catalogues. Two pages from a Baedeker published in Lyra's world, a postcard from the character Mary Malone, and a brochure for the cruise shipZenobia are also included. The postcard contains four images of sites in the His Dark Materials trilogy: the physics lab in which Mary Malone works, the house occupied by Lord Boreal, the row of hornbeam trees where Will first discovered a window between the worlds, and the bench where Lyra and Will have pledged to visit each other in spirit once a year. The preface by Pullman begins:
Lyra is looking at a flock of birds from the tower of Jordan College in her Oxford, when she notices that the birds are attacking what turns out to be a dæmon in a bird shape. This dæmon must be a witch's because there is no human near. Lyra saves the dæmon, called Ragi, from the flock, and he urges Lyra to help him find a man called Sebastian Makepeace. Lyra cleverly finds out where to find him and that he is the last remaining alchemist, and promises Ragi to bring him to the alchemist after school. In the evening, Lyra escapes from St Sophia's School and leads Ragi from outside Jordan College to Juxon Street where Sebastian Makepeace lives. Ragi flies above Lyra and hides on roofs to avoid suspicion. On the way, Ragi is attacked by some pigeons, but manages to save himself. Ragi also tells Lyra why he needs Sebastian Makepeace's help: his witch, Yelena Pazhets, is seriously ill. This new illness causes witches to die while not affecting their dæmons, leaving them alive and lonely after their witch's death. Lyra is shocked by this. Reaching Makepeace's house at the end of Juxon Street, near the Oxford Canal, Lyra's dæmon Pantalaimon manages to look through Makepeace's window without being noticed by Ragi. Pan sees the alchemist lying on the floor and witch's instruments nearby. Sensing something is wrong, Lyra continues walking, past Makepeace's house, at which Ragi cries for his witch. Lyra realises it was a trap and now finds herself being attacked by the witch. She moves towards the canal and decides to fight the witch, because this is what Will would do. When Yelena charges, a swan rushes past Lyra and attacks the witch. The witch dies shortly after. Lyra carries the swan back to the canal, after which a recovered Sebastian Makepeace takes her into his house and explains that Yelena wanted to kill Lyra and blame him for the murder: Yelena was once Sebastian's lover and their son died in the war that was waged in The Amber Spyglass. Yelena blamed Lyra for her son's death. Sebastian helps to get Lyra away unnoticed and she gets back to St Sophia's. Back home Lyra and Pan contemplate that day's events: the birds were actually helping her and, looking for some meaning behind the events, Lyra feels that Oxford is protecting her.
