Both of them replied that the prince had returned on the previous evening about nightfall, after having been disturbed at an inconvenient hour by Monsieur du Bouchage, who had arrived with a message from the king.

They then added that when the audience had terminated, which had been held in the chateau itself, the prince had ordered supper to be prepared, and had desired that no one should venture to approach the pavilion without being summoned; and lastly, that he had given the strictest injunctions not to be awakened in the morning, and that no one should enter without a positive summons.

“He probably expected a visit from a lady?” observed the queen-mother, inquiringly.

“We think so, madame,” replied the valet respectfully, “but we could not discreetly assure ourselves of the fact.”

“But in removing the things from the table, you must have seen whether my son had supped alone?”

“We have not yet removed the things, madame, since the orders of monseigneur were that no one should enter the pavilion.”

“Very good,” said Catherine; “no one, therefore, has been here?”

“No one, madame.”

“You may go.”

And Catherine was now left quite alone in the room.  Leaving the prince lying on the bed where he had been placed, she immediately commenced the minutest investigation of each symptom or of each of the traces to which her attention was directed, as the result of her suspicions or apprehensions.

She had remarked that Francois’ forehead was stained or dyed of a bister color, his eyes were bloodshot and encircled with blue lines, his lips marked with furrows, like the impression which burning sulphur leaves on living flesh.

She observed the same sign upon his nostrils and upon the sides of the nose.

“Now let me look carefully,” she said, gazing about her on every side.

The first thing she remarked was the candlestick in which the flambeau which Remy had lighted the previous evening had burned away.

“This candle has burned for a length of time,” she said, “and shows that Francois was a long time in this room.  Ah! here is a bouquet lying on the carpet.”

Catherine picked it up eagerly, and then, remarking that all its flowers were still fresh, with the exception of a rose, which was blackened and dried up: 

“What does this mean?” she said; “what has been poured on the leaves of this flower?  If I am not mistaken, I know a liquid which withers roses in this manner.”  She threw aside the bouquet, shuddering as she did so.

“That explains to me the state of the nostrils and the manner in which the flesh of the face is affected; but the lips?”

Catherine ran to the dining-room.  The valets had spoken the truth, for there was nothing to indicate that anything on the table had been touched since the previous evening’s repast had been finished.
