"I have an idea of my own about the jewels. Tell me, Messieurs, what do you know of a man called the Marquis?"
The Commissary leant forward excitedly.
"The Marquis," he said, "the Marquis? Do you think he is mixed up in this affair, M. Poirot?"
"I ask you what you know of him."
The Commissary made an expressive grimace.
"Not as much as we should like to," he observed ruefully. "He works behind the scenes, you understand. He has underlings who do his dirty work for him. But he is some one high up. That we are sure of. He does not come from the criminal classes."
"A Frenchman?" "Y—es. At least we believe so. But we are not sure. He has worked in France, in England, in America. There was a series of robberies in Switzerland last autumn which were laid at his door. By all accounts he is a grand seigneur, speaking French and English with equal perfection and his origin is a mystery."
Poirot nodded and rose to take his departure.
"Can you tell us nothing more, M. Poirot," urged the Commissary.
"At present, no," said Poirot, "but I may have news awaiting me at my hotel."
M. Carrège looked uncomfortable. "If the Marquis is concerned in this" he began, and then stopped.
"It upsets our ideas," complained M. Caux.
"It does not upset mine," said Poirot. "On the contrary, I think it agrees with them very well. Au revoir, Messieurs; if news of any importance comes to me I will communicate it to you immediately."
