"The door was opening again. The seer does not like to dwell upon what he saw entering the room: he says it might be described as a frog – the size of a man – but it had scanty white hair about its head. It was busy about the truckle-beds, but not for long. The sound of cries – faint, as if coming out of a vast distance – but, even so, infinitely appalling,
reached the ear."
M.R. James, The Haunted Dolls' House
