For a moment Leo stood, as if doubtful, without speaking.
"Sarto," he said at last incredulously. "Sarto!"
"Well, Monsieur," said Renan, "shall we not continue our discussion on the future of the Church?"

"Sarto! Sarto!" Renan heard Leo say again, as the clouds gathered about them; and Renan smiled.
"It is clear," he said, "that Sarto is not Leo."
THE END.
