Did anyone ever find the jewelled bunny from Kit Williams book called Masquerade?

http://www.bbc.co.uk/dna/h2g2/pda/A533800 ~ "Masquerade , written by Kit Williams, was of course no ordinary book. Within its pages it concealed the solution to where Kit had buried a bejewelled hare worth £5000. Only Kit and his witness, TV presenter Bamber Gascoigne, knew the golden hare's location. It was a hunt that lasted until February 1982 when 'Ken Thomas' [Ken Thomas was a pseudonym. ] eventually found the treasure."
