Presently she raised her hand to her head, as sometimes one will do unconsciously, and the rose slipped from her hair and dropped to the floor. Both men stooped. Maurice was quickest. With a bow he offered to return it.

“You may keep it, Monsieur;” and she laughed.

They joined her. Maurice knew why the Colonel laughed, and the Colonel knew why Maurice laughed; but neither could account for the laughter of the princess. That was her secret.

Good night; ah, yes, the English fashion,” extending her hand, which Maurice barely touched. “Good night, Monsieur,” to Beauvais, with one of those nods which wither as effectually as frost.

The Colonel bent gracefully.

“Decidedly the Colonel is not in high favor tonight,” thought Maurice; “a fact which is eminently satisfactory to me. Ah; he looks as if he had something to say to me. Let us wait.”

“Monsieur, have you any other engagement this evening?” asked Beauvais, swinging his pelisse over both shoulders. “If not, my rooms are quite handy. I have capital cigars and cognacs. Will you do me the honor? I should like to have you regale me with some Vienna gossip; it is so long since I was there.”

“Thanks,” said Maurice. “I shall be happy to smoke your cigars and drink your cognacs.” He was in the mood for any adventure, comic or serious. He had an idea what the Colonel wanted to say to him, and he was not unwilling to listen. Besides, he had no fear; he now wore an amulet close to his heart.

“Come, then,” said Beauvais, gaily; and the two made off. “It is a wonderful game of chess, this world of ours.”
