The idea, suddenly formed on a word of Des Hermies, that the unknown must be Chantelouve's wife, had, in fashion, checked his fever. If it was she—and his contrary conclusions of the evening before seemed hardly valid when he took up one by one the arguments by which he had arrived at them—then her reasons for wanting him were obscure, dangerous, and he was on his guard, no longer letting himself go in complete self-abandon.

And yet, there was another phenomenon taking place within him. He had never paid any especial attention to Hyacinthe Chantelouve, he had never been in love with her. She interested him by the mystery of her person and her life, but outside her drawing-room he had never given her a thought. Now ruminating about her he began almost to desire her.

Suddenly she benefited by the face of the unknown, for when Durtal evoked her she came confused to his sight, her physiognomy mingled with that which he had visualized when the first letters came.

Though the sneaking scoundrelism of her husband displeased him, he did not think her the less attractive, but his desires were no longer beyond control. In spite of the distrust which she aroused, she might be an interesting mistress, making up for her barefaced vices by her good grace,

but she was no longer the non-existent, the chimera raised in a moment of uncertainty.

On the other hand, if his conjectures were false, if it was not Mme. Chantelouve who had written the letters, then the other, the unknown, lost a little of her subtlety by the mere fact that she could be incarnated in a creature whom he knew. Still remote, she became less so; then her beauty deteriorated, because, in turn, she took on certain features of Mme. Chantelouve, and if the latter had profited, the former, on the contrary, lost by the confusion which Durtal had established.

In one as in the other case, whether she were Mme. Chantelouve or not, he felt appeased, calmed. At heart he did not know, when he revolved the adventure, whether he preferred his chimera, even diminished, or this Hyacinthe, who at least, in her reality, was not a disenchanting frump, wrinkled with age. He profited by the respite to get back to work, but he had presumed too much upon his powers. When he tried to begin his chapter on the crimes of Gilles de Rais he discovered that he was incapable of sewing two sentences together. He wandered in pursuit of the Marshal and caught up with him, but the prose in which he wished to embody the man remained listless and lifeless, and he could think only patchily.

He threw down his pen and sank into an armchair. In revery he was transported to Tiffauges, where Satan, who had refused so obstinately to show himself, now became incarnate in the unwitting Marshal, to wallow him, vociferating, in the joys of murder.

"For this, basically, is what Satanism is," said Durtal to himself. "The external semblance of the Demon is a minor matter. He has no need of exhibiting himself in human or bestial form to attest his presence. For him to prove himself, it is enough that he choose a domicile in souls which he ulcerates and incites to inexplicable crimes. Then, he can hold his victims by that hope which he breathes into them, that instead of living in them as he does, and as they don't

often know, he will obey evocations, appear to them, and deal out, duly, legally, the advantages he concedes in exchange for certain forfeits. Our very willingness to make a pact with him must be able often to produce his infusion into us.
