But try as Williams would, he could not make his neighbour speak of anything profound or hidden. The old man would not live up to his aspect and manner, but would feign a smile and a light tone and prattle feverishly and frantically of cheerful trifles; his voice every moment rising and thickening till at last it would split in a piping and incoherent falsetto. That his learning was deep and thorough, his most trivial remarks made abundantly clear; and Williams was not surprised to hear that he had been to Harrow and Oxford. Later it developed that he was none other than Lord Northam, of whose ancient hereditary castle on the Yorkshire coast so many odd things were told; but when Williams tried to talk of the castle, and of its reputed Roman origin, he refused to admit that there was anything unusual about it. He even tittered shrilly when the subject of the supposed under crypts, hewn out of the solid crag that frowns on the North Sea, was brought up.
