The city provided the inspiration for the fictional Jordan College in Pullman's His Dark Materials trilogy. The writer explains how his childhood and student days have fed into the imagined worlds of his books. Critics and literary experts also contribute, sharing their own insights into Pullman's work, including I Was a Rat! and the Sally Lockhart adventures.
