"... I have still never seen a ghost for myself, even in the shadier vaults of the British Museum, where the ancient dead can lie peacefully, and many of the living have witnessed strange things. Sometimes I have crouched immobile in the evening darkness at the top level of our Victorian Arched Room library, like a wildlife photographer at a waterhole, waiting in silence for a spectral figure who has, they say, more than once been observed. For me, though, no shady visitor."
