Praise for The Watcher in the Shadows:
"Zafón cuts between his various characters with cinematic skill, and his habit of telling stories within the narrative is put to spine-tingling use...Good, solid scares."—Booklist
"Exciting...Plenty of thrills and chills."—Publishers Weekly
—The Horn Book
"A clever plot, sympathetic characters, and a richly detailed 1930s setting; a haunted, melancholy tone with an air of nostalgia and an atmosphere of menace."
