A ghostly story

This is the top floor of the famous Eagle pub in Cambridge. In this pub, the discoverers of DNA used to dine together six days a week. There is a legend that a fire raged through the upstairs bedrooms a few hundred years ago and a young child, unable to open the window, was trapped inside and burnt to death. Ever since, the window has been kept open, and on occasions when it has been closed, it has brought bad luck, or has mysteriously opened itself. It's even claimed that it is now written into the lease that the window must always remain open.
