"Proofs! give me proof!" cried the Baron, almost crazy with exasperation.

"Come, and you shall have them," said Crevel.

And in obedience to Valerie's instructions, he led the Baron away towards the quay, down the Rue Hillerin-Bertin. The unhappy Baron walked on, as a merchant walks on the day before he stops payment; he was lost in conjectures as to the reasons of the depravity buried in the depths of Valerie's heart, and still believed himself the victim of some practical joke. As they crossed the Pont Royal, life seemed to him so blank, so utterly a void, and so out of joint from his financial difficulties, that he was within an ace of yielding to the evil prompting that bid him fling Crevel into the river and throw himself in after.

On reaching the Rue du Dauphin, which had not yet been widened, Crevel stopped before a door in a wall. It opened into a long corridor paved with black-and-white marble, and serving as an entrance-hall, at the end of which there was a flight of stairs and a doorkeeper's lodge, lighted from an inner courtyard, as is often the case in Paris. This courtyard, which was shared with another house, was oddly divided into two unequal portions. Crevel's little house, for he owned it, had additional rooms with a glass skylight, built out on to the adjoining plot, under conditions that it should have no story added above the ground floor, so that the structure was entirely hidden by the lodge and the projecting mass of the staircase.

This back building had long served as a store-room, backshop, and kitchen to one of the shops facing the street. Crevel had cut off these three rooms from the rest of the ground floor, and Grindot had transformed them into an inexpensive private residence. There were two ways in—from the front, through the shop of a furniture-dealer, to whom Crevel let it at a low price, and only from month to month, so as to be able to get rid of him in case of his telling tales, and also through a door in the wall of the passage, so ingeniously hidden as to be almost invisible. The little apartment, comprising a dining-room, drawing-room, and bedroom, all lighted from above, and standing partly on Crevel's ground and partly on his neighbor's, was very difficult to find. With the exception of the second-hand furniture-dealer, the tenants knew nothing of the existence of this little paradise.

The doorkeeper, paid to keep Crevel's secrets, was a capital cook. So Monsieur le Maire could go in and out of his inexpensive retreat at any hour of the night without any fear of being spied upon. By day, a lady, dressed as Paris women dress to go shopping, and having a key, ran no risk in coming to Crevel's lodgings; she would stop to look at the cheapened goods, ask the price, go into the shop, and come out again, without exciting the smallest suspicion if any one should happen to meet her.

As soon as Crevel had lighted the candles in the sitting-room, the Baron was surprised at the elegance and refinement it displayed. The perfumer had given the architect a free hand, and Grindot had done himself credit by fittings in the Pompadour style, which had in fact cost sixty thousand francs.

"What I want," said Crevel to Grindot, "is that a duchess, if I brought one there, should be surprised at it."

He wanted to have a perfect Parisian Eden for his Eve, his "real lady," his Valerie, his duchess.

"There are two beds," said Crevel to Hulot, showing him a sofa that could be made wide enough by pulling out a drawer. "This is one, the other is in the bedroom. We can both spend the night here."
