Sir Hugh Ockram smiled as he sat by the open window of his study, in the late August afternoon; and just then a curiously yellow cloud obscured the low sun, and the clear summer light turned lurid, as if it had been suddenly poisoned and polluted by the foul vapours of a plague. Sir Hugh's face seemed, at best, to be made of fine parchment drawn skin-tight over a wooden mask, in which two eyes were sunk out of sight, and peered from far within through crevices under the slanting, wrinkled lids, alive and watchful like two toads in their holes, side by side and exactly alike. But as the light changed, then a little yellow glare flashed in each. Nurse Macdonald said once that when Sir Hugh smiled he saw the faces of two women in hell-two dead women he had betrayed.
