She shook her head.
"Sir John Dory," Peter continued. "He came here with a request. He begged for my help. Guillot is here, committed to some enterprise which no man can wholly fathom. Dory has enough to do with other things, as you can imagine, just now. Besides, I think he recognises that Monsieur Guillot is rather a hard nut for the ordinary English detective to crack."
"And you?" she demanded, breathlessly.
"I join forces with Dory," Peter admitted. "Sogrange agrees with me. Guillot was associated with the Double Four too long for us to have him make scandalous history, either here or in Paris."
"You have seen him?"
"I have not only seen him," Peter said, "I have 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.
