Some 170 years ago, "The Guardsman" was an officer's mess and gambling room for the Duke of Wellington's regiment based in Knightsbridge, London. According to the legend, a young officer, playing cards, was caught cheating and attacked by his fellow officers. They stripped him and flogged the skin from his body, leaving him to die in the cellar.
"The Guardsman" is now the "Grenadier" public house, where several landlords have reported a cyclical ghost whose appearances recur in September, around the anniversary of the young man's death. In some cases it's described as being "an indefinitable but definite atmosphere"; it has affected both people and animals and there have been sightings. One landlord's son saw a black shape outside his bedroom one September evening and his mother also saw a figure climbinb the stairs who suddenly disappeared. A visitor to the public house once saw a figure by the side of the bed in the middle of the night which then disappeared.
Another landlord, Geoffrey Bernard, reported poltergeist activity and shadows during the month of September. John Spencer visited the house in January 1991 and spoke to the present manager/licensee, Peter Martin, and two of his staff, Sara McCarthy and Kathy McVey.
Peter Martin told of one occasion when he was n the bar at around midnight with a Mr Edward Webber. They saw a bottle apparently lift from approximately one foot abover floor height, where the 'mixers' are stored to around head hight in the middle of the bar area where it exploded. Martin also told of several occasions when keys would go mysteriously missing and then turn up, equally mysteriously. On one occason in 1988 or 1989 some electricians had arrived to do electrical repair work in the cellar. The keys to the cellar where the electricians were to work were found to be missing. They were usually kept under the mattress on Martin's bed but were not there when he looked for them. Eventually the keys were found but would not open the locks despite all the efforts made to open them. A street cleaner who was a friend of the electricians assisted them and was apparently able to open the lock with no effort whatsoever. At the time of John Spencer's visit the street cleaner had apparently retired and his whereabouts were not known.
Peter Martin had come over to the pub in January 1988 as the relief manager and took over as manager in Febuary 1990/ Since that later date he has experienced no sightings.
He did make the point that ghost activity could easily be missed. Sometime between July and September of 1991 there was a break in at the pub between four and seven o' clock in the morning. Despite the fact that several people where then sleeping in the building, noone heard the break in.

Could be a fact.
The funny thing is when I was in the UK every pub told me a similar story but changed the identity of the ghost.
At Ensign Ewarts Pub in Edinburgh for instance, the ghost was a lone piper who after being deserted by his troops now plays his ghostly tunes on his pipes from the basement of the pub.
The pub called "The end of the world" in Edinburgh has a similar story, and I heard similar stories in London and even Holland.

This leaves me wondering if the ghostly tales are authentic, or just a muse to attract tourists.
