An hour afterwards Valentine and M. de Luceval rejoined each other in the cab which had deposited them a short distance from the two adjoining houses where their search was to be conducted.

"Ah, well, monsieur, what news?" asked Madame d'Infreville, who, pale and agitated, had been the first to return to the vehicle.

"There can no longer be any doubt that my wife suspects the truth, madame. I told the porter that I wished to see Madame de Luceval on very important business. 'That lady no longer resides here, monsieur,' the man replied. 'She came in a carriage about eleven o'clock and took away several bundles and packages, at the same time informing me that she had no intention of returning again. Madame de Luceval has paid her rent six months in advance ever since she came here, and some time ago she gave notice of her intention to leave on the first of June. As for the few articles of furniture that she owns, she is to let us know what disposal we are to make of them.' It was impossible to get anything more out of the man. And you, madame, what did you find out?"

"Almost the very same thing that you did, monsieur," replied Valentine, despondently. "Michel returned home about eleven o'clock. He, too, informed the porter of his intention of leaving the house, and promised to let him know what disposition to make of his furniture. He, too, had notified the landlord of his intention of giving up his rooms on the first of June."

"Then it is on the first of June that they are to be united?"

"But in that case why do they make an appointment with me for the same date?"

"Whatever they may say, and whatever they may do, I am determined to solve this mystery!" exclaimed M. de Luceval.

Madame d'Infreville's only response was a melancholy shake of the head.

CHAPTER XVI.
AN IDLER'S PARADISE.

IT was about three months after M. de Luceval and Madame d'Infreville met in Paris, when the events we are about to relate occurred at a modest villa near the town of Hyères, in Provence.
