It was a chill, rain-washed afternoon of a late August day, that indefinite season when partridges are still in security or cold storage, and there is nothing to hunt - unless one is bounded on the north by the Bristol Channel, in which case one may lawfully gallop after fat red stags. Lady Blemley's house- party was not bounded on the north by the Bristol Channel, hence there was a full gathering of her guests round the tea-table on this particular afternoon. And, in spite of the blankness of the season and the triteness of the occasion, there was no trace in the company of that fatigued restlessness which means a dread of the pianola and a subdued hankering for auction bridge. The undisguised open-mouthed attention of the entire party was fixed on the homely negative personality of Mr. Cornelius Appin. Of all her guests, he was the one who had come to Lady Blemley with the vaguest reputation. Some one had said he was "clever," and he had got his invitation in the moderate expectation, on the part of his hostess, that some portion at least of his cleverness would be contributed to the general entertainment. Until tea-time that day she had been unable to discover in what direction, if any, his cleverness lay. He was neither a wit nor a croquet champion, a hypnotic force nor a begetter of amateur theatricals. Neither did his exterior suggest the sort of man in whom women are willing to pardon a generous measure of mental deficiency. He had subsided into mere Mr. Appin, and the Cornelius seemed a piece of transparent baptismal bluff. And now he was claiming to have launched on the world a discovery beside which the invention of gunpowder, of the printing-press, and of steam locomotion were inconsiderable trifles. Science had made bewildering strides in many directions during recent decades, but this thing seemed to belong to the domain of miracle rather than to scientific achievement.
