The Countess Maravitz had evinced a strong liking for her, bringing, so she said, a verbal introduction from Mrs. Hawkesley--once Lady Chepstow--whose son both Ailsa and Cleek had saved from imminent peril. Cleek's senses, quickened by the information given him by Dollops, noticed almost mechanically that although the number of guests was large they consisted mainly of men. There were very few women, and such as were present were decidedly of foreign aspect. Polish, Belgian--and French. Cleek's heart sank and then pounded violently as his eyes rested on a slender, white-gowned figure shaking hands with their hostess. It was Ailsa, and as several of the guests closed round the group it seemed already to Cleek's strained nerves as if they were closing in on the one woman in the world. A feeling came over him that right well had they played into their enemies' hands. Would they live to emerge safe? Cleek's fingers tightened instinctively on the pistol in his pocket. Almost he felt inclined to dash forward and at its point to bear Ailsa out of the house into safety. He blamed himself for his blindness--blamed even Dollops for not speaking out before. Quietly and as unconcernedly as usual, however, to all outward mien, he sauntered across the great ballroom, and gently insinuated his way to Ailsa, who greeted him with that smile of infinite trust that always pierced his very heart. The thought that her life should be in danger because of him was one of his greatest sorrows. Giving her his arm and in the buzz of talk and laughter, as they commenced to dance a few minutes later, he contrived to whisper: "Dearest, be brave! I fear we are in danger. Keep as close to me as possible and make some excuse to leave early. Laugh now if you can. I feel sure that that woman is watching us!" "That woman" was the Polish countess, and she was indeed watching them. Just then, whether impelled by the signal of Ailsa's paling and flushing face, or because she actually read the movements of Cleek's lips, she glided over to them as they came to a standstill at one side of the ballroom. "Ah, _mes amis_, but you dance so beautifully! You are tired, eh? Miss Lorne, come, do me the pleasure of seeing some pictures of my countrymen. They came to-day!" She opened a small and almost hidden door behind her and, not knowing for the moment what else to do, Ailsa, with Cleek close behind, followed her as she stepped through the doorway. The room was almost dark, and, blinded by the sudden transition from the brilliantly lighted ballroom, Ailsa stopped short, but too late! The door closed behind them with a little vicious click, and as the Countess gave a low laugh of infinite triumph she switched on the lights. The sudden blaze revealed the presence of half a dozen men, guards evidently, and as Cleek recognized the familiar brand of his implacable enemies, the Paris Apaches, his heart sank.
