Masquerade is a picture book, written and illustrated by Kit Williams and published in August 1979, that sparked a treasure hunt by including concealed clues to the location of a jewelled golden hare that had been created and hidden somewhere in Britain by Williams. The book became the inspiration for a genre of books known today as armchair treasure hunts. In March 1982 Williams received a letter and sketch from a man called Dugald Thompson, which he acknowledged as the first correct solution to the puzzle, meaning that Thompson had won the contest. It was later found that Thompson had not solved the puzzle and had guessed the hare's location using insider knowledge obtained from a former acquaintance of Williams. The revelation caused a minor scandal. Two British physics teachers were later acknowledged to be the first to have correctly solved the puzzle. Book In the 1970s, Williams was challenged by Tom Maschler, of the British publishing firm Jonathan Cape, to do "something no one has ever done before" with a picture book. Williams set out to create a book that readers would study carefully rather than flip through and then discard. The book's theme, a hunt for a valuable treasure, became his means to this end. Masquerade contains fifteen detailed paintings that illustrate the story of a hare named Jack Hare, who seeks to carry a treasure from the Moon (depicted as a woman) to the Sun (depicted as a man). On reaching the Sun, Jack finds that he has lost the treasure, and the reader is challenged to discover its location. Along with creating the book, Williams crafted 18-carat (75%) gold and jewels into a large filigree pendant in the shape of a hare. He sealed the hare inside a small ceramic casket, both to protect the prize from soil and to foil attempts to locate the treasure using a metal detector. The casket was inscribed with the legend "I am the keeper of the jewel of Masquerade, which lies waiting safe inside me for you or eternity". Kit Williams later said: If I was to spend two years on the sixteen paintings for Masquerade I wanted them to mean something. I recalled how, as a child, I had come across "treasure hunts" in which the puzzles were not exciting nor the treasure worth finding. So I decided to make a real treasure, of gold, bury it in
