The Ladderless Window-Cleaning Company certainly doesn't. They don’t need a pail, either, because they have a pelican with a bucket-sized beak. With a monkey to do the washing and Billy as their manager, this business is destined for success. Now they have their big break—a chance to clean all 677 windows of the Hampshire House, owned by the richest man in all of England! That’s exciting enough, but along the way there are surprises and adventures beyond their wildest window-washing dreams.
