In an abandoned mansion at the heart of Barcelona, a young man, David Martin, makes his living by writing sensationalist novels under a pseudonym. The survivor of a troubled childhood, he has taken refuge in the world of books and spends his nights spinning baroque tales about the city's underworld.

But perhaps his dark imaginings are not as strange as they seem, for in a locked room deep within the house lie photographs and letters hinting at the mysterious death of the previous owner.  

Once again, Zafon takes us into a dark, gothic universe first seen in the Shadow of the Wind and creates a breathtaking adventure of intrigue, romance, and tragedy. Through a dizzingly constructed labyrinth of secrets, the magic of books, passion, and friendship blend into a masterful story.
