The doctor spoke in a whisper to himself, each short sentence was succeeded by a chortle, a subdued chuckle. "The arm of coincidence is long! The cursed Anglo-Saxon is proud--very proud, but he is a very simple fool. One of them is dead. It may be this young fool's turn next. Gilda loves him, too. That is a pity. Yet it must be." These soft-spoken reflections, with the drug, seemed to pacify the perturbed mind of this extraordinary man, and he appeared to doze for a while. Presently he sprang to his feet and his frame displayed surprising activity. Taking Raife's keys in one hand, he opened a valise, from which it was evident that he had travelled much. Yet the labels of hotels, cities, and townships had been so cleverly manipulated, that they were hard to decipher. Opening the valise, he produced some wax, on which, with the dexterity of a practised hand, he took the impressions of the keys of Aldborough Park. It was late when the doctor had completed his task. The first grey streaks of dawn crept through the long curtained windows, as he stealthily opened the door of his room. Surveying the silent corridor with care, he stole stealthily to Gilda's room and tapped gently. The frightened girl, accustomed to the strange demands of her uncanny uncle, replied with surprising promptitude. He hastily thrust Raife's keys into her hand, muttering: "Give these back to the young fool, and see to it you don't lose your head. I will meet you in the coffee-room at ten o'clock, and you can introduce him to me." At ten o'clock on the morning following these occurrences which appeared of such evil portent, Gilda Tempest, daintily clad in a light gown of soft material in which chiffon seemed to predominate, walked into the coffee-room of the hotel and took her seat at a table, laid for three, next to a window which commanded a view of the Promenade des Anglais. The doctor had planned the arrangement of this table with that prescience which characterised all his movements. She had not been seated many minutes, and was sipping some coffee--the coffee that, in spite of modern facilities, seems to be only obtainable on the continent of Europe, when Sir Raife Remington entered the room. He crossed to the table at which Gilda was seated and greeted her. To his pleasure and astonishment she said, heartily: "Good morning. Sir Raife. Won't you take a seat at our table? I expect my uncle, presently, and he will be very pleased to see you. First of all, let me thank you for the loan of your keys. It was so distressing, I could not find my keys anywhere, and, in desperation, I thought of your kind offer to help me if I needed it." Raife laughed heartily, and, taking a seat opposite to her, said: "Please don't thank me for a small thing like that. I meant, more especially, I would like to help you in something big, as the Americans would say--something real large, should the occasion arise."
