Ghost Sighting Somerset Shepton Mallet

We bought an old thatched Restaurant in Shepton Mallet in 1982 . The first morning there we woke up to a light going around every wall in our bedroom. Then every time I went in to the ladies toilets to check the cleaning all the lights would go off.Finally my husband saw the ghost one night walking along in the hall downstairs . Next day we put it up for sale ,we told the staff who replied they knew about the grey lady who haunted the place.We bought and sold within 3 months
