The Fire Station Visitor was said to have walked through closed doors, lower the temperature of the central heating and then vanish all of a sudden.
A cook called Mrs Iris Rhodes saw it three times and once even chased it down the stairs with a glass of water thinking it was a fireman playing a prank. She described the ghoul as between thirty and thirty six, with ruddy cheeks and wearing a large mackintosh - but there could be another explanation...
The Temple area of Bristol was once owned by the Knight Templars, an order of warrior monks suppressed in 1308 for heresy - in reality because they had become too powerful for medieval Kings and Popes to control.
While Mrs Rhodes believed it was wearing a mac, firemen who saw him reckoned it was actually medieval dress. The theory is it was one of the knights keeping an eye on development on the Templars' estate.
