A clock on each of the four floors and none of them tells the same time! Or so thinks Mr. Higgins as he dashes from hall -- ""Twenty minutes past four"" -- up to attic -- ""twenty-three minutes past four"" -- down two flights to kitchen -- ""twenty-five minutes past four"" -- and up one to bedroom -- ""twenty-six minutes past four."" Whether the youngster spots the time-lapse or, with Mr. Higgins, defers to the moving hands of the Clockmaker's watch (""What a wonderful watch!"") hardly matters: the Kate Greenaway environs, the cutaways of the four-story, four-clock house, and Mr. Higgins' what-the-Dickens? disconcertion guarantee a good time for all.
