Scene
The Lisbon Book Fair on a warm afternoon, rows of white tents stretching as far as the eye can see, books from every corner of the world on display. Hundreds of readers wander between the stalls — deep in a tent of obscure crime novels, someone hasn't just opened a book. They've stumbled into a real mystery.
