He spoke and vanished, either into the street crowd or into thin air.

You may recall the story of the "Man in Black's" midnight visit to Ninon de l'Enclos, with a gift to the essence of youth and the warning of her death? This was a well-believed and oft-repeated narrative in Marie's day. It is highly possible that she built from it her recital of the adventure of the "elegantly attired" stranger.

At all events, she told Jean du Barry about it. Whether or not he believed it, is no concern of yours or mine. But it assuredly gave him an idea; the supreme idea of his rotten life. He saw a one-in-fifty chance of making more money through Marie than she could have earned for him in a century as divinity of his gambling rooms. And, remote as were the scheme's prospects for success, he resolved to make a gambler's cast at the venture.

Louis XV., King of France, had been ruled for nearly twenty years by the Marquise de Pompadour, who had squandered royal revenues, had made and unmade men's career by a nod or a shake of her pretty head, and had played at ducks and drakes with international politics. And now Madame de Pompadour was dead. Many a younger and prettier face had caught Louis' doddering fancy, since her death. But no other maitresse en titre had ruled him and France since then.

Briefly, Jean coveted the vacant office for Marie.

Not for her own sake. Jean did not care for her happiness or welfare, or for the happiness or welfare of any mortal on earth except of one Jean, Vicomte du Barry. But he foresaw that with Marie as the royal favorite, he himself, as her sponsor, could reap a harvest such as is not the guerdon of one man in a million.

He set to work at his self-appointed task with the same rare vigor and cunning that had so long enabled him to elude the hangman and to live on better men's money. The first step was to engage the help of Lebel, the king's valet de chambre.

Lebel was nominally a servant, but, in a sense, he was mightier than any prime minister. For Louis relied implicitly on the valet's taste in feminine beauty. It was Lebel, for instance, who had first brought Madame du Pompadour to the king's notice. He had done the same good turn to many another aspiring damsel. And now, heavily bribed by Jean du Barry, he consented to see if Marie was worth mentioning to Louis.

At sight of Marie, the connoisseur valet realized to the full her super-woman charm. He recognized her as the thousandth woman—even the millionth.

Yet Lebel was ever cautious about raising false hopes. So, not knowing that Jean had gone over the whole plan with Marie, he asked her if she would honor him by attending a little informal dinner he was soon to give, in his apartment, at the Versailles palace; a dinner in honor of "the Baron de Gonesse."
