Christopher 'Kit' Williams (born 28 April 1946 in Kent, England) is an English artist, illustrator and author best known for his 1979 book Masquerade (Wikipedia page ), a pictorial storybook which contains clues to the location of a golden (18 carat) jeweled hare created by Williams and then buried "somewhere in Britain".
Williams wrote another puzzle book with a bee theme; the puzzle was to figure out the title of the book and represent it without using the written word. This competition ran for just a year and a day and the winner was revealed on the live BBC TV chatshow Wogan.
