Peter hesitated.

"Monsieur de Lamborne," he said, "the room adjoining is your wife's?"

"It is the salon of madame," the Ambassador admitted.

"What are the electrical appliances doing there?" Peter demanded. "Don't look at me like that, de Lamborne. Remember that I was here before you arrived."

"My wife takes an electric massage every day," Monsieur de Lamborne answered in a hard, unnatural voice. "In what way is Monsieur le Baron concerned in my wife's doings?"

"I think that there need be no answer to that question," Peter said quietly. "It is a greater tragedy which we have to face. I maintain that your safe was entered from that room. A search will prove it."

"There will be no search there," de Lamborne declared fiercely. "I am the ambassador of France, and my power under this roof is absolute. I say that you shall not cross that threshold."

Peter's expression did not change. Only his hands were suddenly outstretched with a curious gesture—the four fingers were raised, the thumbs depressed. Monsieur de Lamborne collapsed.

"I submit," he muttered. "It is you who are the master. Search where you will."
