Scarcely had he recovered, when he resolved to pass the night in the very spot where these terrible mysteries were enacted, and to take the subtle and dangerous visitors by surprise. It was an enterprise that demanded all his slender courage. Being a man of delicate physique and of nervous temperament, Monsieur Sariette was naturally inclined to be fearful. On the 8th of January at nine o'clock in the evening, while the city lay asleep under a whirling snowstorm, he built up a good fire in the room containing the busts of the ancient poets and philosophers, and ensconced himself in an arm-chair at the chimney corner, a rug over his knees. On a small stand within reach of his hand were a lamp, a bowl of black coffee, and a revolver borrowed from the youthful Maurice. He tried to read his paper, La Croix, but the letters danced beneath his eyes. So he stared hard in front of him, saw nothing but the shadows, heard nothing but the wind, and fell asleep.

When he awoke the fire was out, the lamp was extinguished, leaving an acrid smell behind. But all around, the darkness was filled with milky brightness and phosphorescent lights. He thought he saw something flutter on the table. Stricken to the marrow with cold and terror, but upheld by a resolve stronger than any fear, he rose, approached the table, and passed his hands over the cloth. He saw nothing; even the lights faded, but under his fingers he felt a folio wide open; he tried to close it, the book resisted, jumped up and hit the imprudent librarian three blows on the head.

Monsieur Sariette fell down unconscious....

Since then things had gone from bad to worse. Books left their allotted shelves in greater profusion than ever, and sometimes it was impossible to replace them; they disappeared. Monsieur Sariette discovered fresh losses daily. The Bollandists were now an imperfect set, thirty volumes of exegesis were missing. He himself had become unrecognisable. His face had shrunk to the size of one's fist and grown yellow as a lemon, his neck was elongated out of all proportion, his shoulders drooped, the clothes he wore hung on him as on a peg. He ate nothing, and at the CrÈmerie des Quatre ÉvÊques he would sit with dull eyes and bowed head, staring fixedly and vacantly at the saucer where, in a muddy juice, floated his stewed prunes. He did not hear old Guinardon relate how he had at last begun to restore the Delacroix paintings at St. Sulpice.

Monsieur RenÉ d'Esparvieu, when he heard the unhappy curator's alarming reports, used to answer drily:

"These books have been mislaid, they are not lost; look carefully, Monsieur Sariette, look carefully and you will find them."

And he murmured behind the old man's back:

"Poor old Sariette is in a bad way."

"I think," replied AbbÉ Patouille, "that his brain is going."
