"Reginald Musgrave had been in the same college as myself, and I had some slight acquaintance with him. He was not generally popular among the undergraduates, though it always seemed to me that what was set down as pride was really an attempt to cover extreme natural diffidence. In appearance he was a man of an exceedingly aristocratic type, thin, high-nosed, and large-eyed, with languid and yet courtly manners. He was indeed a scion of one of the very oldest families in the kingdom, though his branch was a cadet one which had separated from the Northern Musgraves some time in the sixteenth century, and had established itself in Western Sussex, where the manor house of Hurlstone is perhaps the oldest inhabited building in the county.
