The faceless gentleman does not seem to be a demon at first, but there definitely seems to be something wrong with him. The tasks he gives Milo, Tock, and the Humbug seem unimportant and time consuming. Juster seems to be setting us up for a revelation about the gentleman, a technique called foreshadowing. Though we aren't certain just what he is up to yet, Juster has given us a lot of clues that suggest the gentleman has something up his sleeves.
