William Lyttle is a 77 year old pensioner from east London. For over 40 years he dug a labyrinth of tunnels under his house in Mortimer Road, Hackney.
(The eccentric Mr Lyttle, aka Mole Man, has since been ordered to pay £300,000 for repairs carried out to stabilise the house. He was lucky not to be sent to prison, but I guess they thought he might dig his way out.)
