“I have not only seen him, but declared war against him.”

“And he?”

“Guillot is defiant,” Peter replied. “He has been here only this evening. He mocks at me. He swears that he will bring off this enterprise, whatever it may be, before midnight to-night, and he has defied me to stop him.”

“But you will,” she murmured, softly.

Peter smiled. The conviction in his wife’s tone was a subtle compliment which he did not fail to appreciate.

“I have hopes,” he confessed, “and yet, let me tell you this, Violet. I have never been more puzzled. Ask yourself, now. What enterprise is there worthy of a man like Guillot, in which he could engage himself here in London between now and midnight? Any ordinary theft is beneath him. The purloining of the crown jewels, perhaps, he might consider, but I don’t think that anything less in the way of robbery would bring him here. He has his code and he is as vain as a peacock. Yet money is at the root of everything he does.”

“How does he spend his time here?” Violet asked.

“He has a handsome flat in Shaftesbury Avenue,” Peter answered, “where he lives, to all appearance, the life of an idle man of fashion. The whole of his spare time is spent with Mademoiselle Louise, the danseuse at the Empire. You see, it is half-past eight now. I have eleven men altogether at work, and according to my last report he was dining with her in the grill-room at the Milan. They have just ordered their coffee ten minutes ago, and the car is waiting outside to take Mademoiselle to the Empire. Guillot’s box is engaged there, as usual. If he proposes to occupy it, he is leaving himself a very narrow margin of time to carry out any enterprise worth speaking of.”

Violet was thoughtful for several moments. Then she crossed the room, took up a copy of an illustrated paper, and brought it across to Peter. He smiled as he glanced at the picture to which she pointed, and the few lines underneath.

“It has struck you, too, then!” he exclaimed. “Good! You have answered me exactly as I hoped. Somehow, I scarcely trusted myself. I have both cars waiting outside. We may need them. You won’t mind coming to the Empire with me?”
