"Such a Highness that, like all princes who belong to the reigning foreign families, he resides in the Élysée-Bourbon during his sojourn in Paris."

Madame Dutertre could not restrain a movement of surprise, and said, after a minute's reflection:

"That is singular."

"What, pray?"

"Antonine lives in a house contiguous to the Élysée. There is nothing very surprising in that, but—"

"But what?"

"I cannot tell you more, Madeleine; when you have heard Antonine's confidences you will comprehend why I have been struck with this coincidence."

"What is there in common with Antonine and the Élysée?"

"I tell you again, my dear friend, wait for the confidences of Antonine."

"So be it, my mysterious friend. Besides, I did not know she lived near the palace. I addressed a letter to her at her old dwelling-house. That suits my plans marvellously; I will go to see her before or after my audience with the prince."
