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.”
