This beautiful building is home to the ghost of Lady Elizabeth Hoby. She is seen to materialise – curiously "in negative" wearing a white dress but with black face and hands – with a basin in front of her, in which she washes her hands. However, we are not dealing with the ghost access to with cleanliness, but by guilt as she washes the bloodstains of her son whom she allegedly murdered from their hands.

The account is a fascinating one and has enthralled ghost hunters for many years. Lady Hoby was born in 1528, at Gidea Hall in Essex and died at Bisham in 1609. She lived during the Elizabethan age and was well-educated woman.

However, it is said that her son lacked her academic prowess and was said to have been mercilessly beaten to death when his mother found he had blotted his work. During renovations in the 19th century, a number of blotted books believed to dating to the Elizabethan era were found in the house. The portrait of Lady Hoby hangs in the Great Hall. In one account, one witness reported seeing her ghost near where her picture was hanging - but the frame was empty of her image. Audible phenomena, including the sound of sobbing, have also been reported.

Other reported phenomena (often attributed to Lady Hoby) include objects thrown around or broken. Her apparition has reportedly been sighted on the lane leading to the main road.
