There was a bicycle repair shop on Hare Lane, Gloucester, back in the day when the bicycle was used as daily transport and one lucky young man, Mr Howell, was taken on at this shop to learn how to repair bicycles. Howell was mainly working in the workshop, which was in the cellar, below the shop. This cellar was said to be connected by a network of tunnels to the Cathedral.
At the time when Howell had his very creepy experience, there were tram lines that were being taken up so there was lots of noise and the shop would shake. This would also attract groups of people who wanted to see what was making all the noise.
The manager asked Howell to go down to the cellar as a bike part was needed for a customer. As Howell went down the wooden stairs, he felt a chill in the air and he thought this was odd as it was a sunny and warm day outside. As he went into the actual cellar, he saw what appeared to be grey mist coming through the brick walls.
