"What is the meaning of this?" the visitor interrupted haughtily. "I am expecting Mademoiselle Louise. I did not understand that strangers had the right of entry into this room." Guillot bowed low. "Monsieur," he said once more, "it is a matter for my eternal regret that I am forced to intrude even for a moment upon an assignation so romantic. But there is a little matter which must first be settled. I have some friends here who have a thing to say to you." He walked softly, with catlike tread, along by the wall to where the thick curtains shut out the inner apartment. He caught at the thick velvet, dragged it back, and the two rooms were suddenly flooded with light. In the recently discovered one, two stalwart-looking men in plain clothes, but of very unmistakable appearance, were standing waiting. Guillot staggered back. They were strangers to him. He was like a man who looks upon a nightmare. His eyes protruded. The words which he tried to utter failed him. Then, with a swift, nervous presentiment, he turned quickly around towards the man who had been standing in the shadows. Here, too, the unexpected had happened. It was Peter, Baron de Grost, who threw his muffler and broad-brimmed hat upon the table. "Five minutes to eleven, I believe, Monsieur Guillot," Peter declared. "I win by an hour and five minutes." Guillot said nothing for several seconds. After all, though, he had great gifts. He recovered alike his power of speech and his composure. "These gentlemen," he said, pointing with his left hand towards the inner room. "I do not understand their presence in my apartments." Peter shrugged his shoulders. "They represent, I am afraid, the obvious end of things," he explained. "You have given me a run for my money, I confess. A Monsieur Guillot who is remarkably like you still occupies your box at the Empire, and Mademoiselle Jeanne Lemère, the accomplished understudy of the lady who has just left us, is sufficiently like the incomparable Louise to escape, perhaps, detection for the first few minutes. But you gave the game away a little, my dear Guillot, when you allowed your quarry to come and gaze even from the shadows of his box at the woman he adored." "Where is--he?" Guillot faltered. "He is on his way back to his country home," Peter replied. "I think that he will be cured of his infatuation for Mademoiselle. The assassins whom you planted in that room are by this time in Bow Street. The price which others beside you knew, my dear Guillot, was placed upon that unfortunate young man's head will not pass this time into your pocket. For the rest----" "The rest is of no consequence," Guillot interrupted, bowing. "I admit that I am vanquished. As for those gentlemen there," he added, waving his hand towards the two men, who had taken a step forward, "I have a little oath which is sacred to me concerning them. I take the liberty, therefore, to admit myself defeated, Monsieur le Baron, and to take my leave."
