Description: Book 151 in the Woongjin World Picture Book series. First published in 1985, this is Anthony Browne's beloved picture book that has watched over children's bedsides for nearly 30 years. Through a single bedroom door, a child's imaginative inner world unfolds, brought to life by Anthony Browne's witty illustrations, creating a bedtime picture book unlike any other. Thanks to the wonderfully distinctive characters Anthony Browne has created, every 'knock knock' brings a fresh mix of suspense and anticipation. And once you discover that all these visitors are secretly the child's loving father in disguise, you can't help but smile. "Knock knock!" Someone is knocking on the door of a child who is alone in their room. "Who's there?" Through the not-yet-open crack in the door, a giant finger prepares to push it open. Goodness, who would believe that a gorilla that big has come to the door? And what about the witch waving her magic wand? Just the sight of a ghost's floppy robe or the puff of smoke from a dragon's breath would make anyone want to dive straight under the covers. But there's no need to worry. Strangely enough, these unwelcome visitors can't come into the room without the child's permission...
