Tonight at 9pm on C4, Tony Robinson of Time Team fame is investigating the case of Helen Duncan, who in England during the 1940s was arrested, tried and jailed under witchcraft laws dating back to 1735.
The psychic had been offering predictions about ships sinking during the Second World War and was considered a threat to national security.
This documentary is the first of three in which Tony Robinson investigates the unexplained. Tomorrow he looks into the ghosts of Glastonbury.
These programmes look as though they should be fascinating viewing for anyone interested in witchcraft, history, the unexplained and English legends.
