"Monsieur," he said, as soon as he saw him, "you must go to the church of Ste. Geneviève; you must descend to the crypt, where you will find the tomb of Cardinal Caprara, and you must bring away the thing, no matter what it is, that you will find on the tomb." M. Decazes went, and when he reached Ste. Geneviève, he went down to the crypt. There, to his great surprise, he found nothing on the tomb of Cardinal Caprara but a fragment of Oriental alabaster. However, his orders were precise: we might rather say they were positive. After a moment's hesitation, he picked up the bit of alabaster and took it back to the Tuileries. He expected the king to jeer at the servile obedience that brought him only an object so worthless, but quite the reverse was the case, for at the sight of the bit of alabaster the king trembled. Then, taking it in his hand and examining it minutely, he placed it on his desk. "Now," said Louis XVIII., "send a trusted messenger to the Royal Library; he must ask for the works of St. Augustine, the 1669 edition, and in volume 7, between pages 404 and 405, he will find a sheet of paper." "But, sire," asked M. Decazes, "why should not I myself go rather than entrust this commission to another?" "Out of the question, _mon enfant_!" "_Mon enfant_" was the pet name by which the king called his favourite minister. A trusted messenger was sent to the Royal Library: he opened St. Augustine at the given pages and found the paper described. It was a simple matter to take it away. The paper was a very thin, blank folio sheet oddly snipped here and there. While Louis XVIII. was searching for the mysterious revelations hidden in the jagged paper the secretary brought him a missive containing a leaf of the same size as that from the St. Augustine, but inscribed with apparently unintelligible letters. At the corner of the envelope in which this leaf came were written the two words: "Most urgent." The king understood that there was a connection between the two events and a likeness between the two leaves. He placed the cut sheet of paper over the written sheet and saw that the letters shown up through the holes in the upper leaf made sense. He dismissed the secretary and intimated to M. Decazes to leave him alone, and when both had gone, he made out the following lines:-- "King, thou art betrayed! Betrayed by thy minister and by the P.P. of thy S----. "King, I alone can save thee. MARIANI." The reader will understand that I do not hold myself responsible for this note any more than for the rest of the anecdote. The king did not mention this note to anyone; but, that evening, the Minister of the Police,[1] who was dismissed next day, issued orders to find a man named Mariani. The following day, which was Sunday the 13th of February, the king on opening his prayer-book at mass found this note inside:--
