The ground was covered with a parqueted flooring of rare wood, forming concentric patterns. Against the walls stood glass cases and a few pictures.

“The pearls of my collection,” said Lupin. “All that you have seen so far is for sale. Things come and things go. That’s business. But here, in this sanctuary, everything is sacred. There is nothing here but choice, essential pieces, the best of the best, priceless things. Look at these jewels, Beautrelet: Chaldean amulets, Egyptian necklaces, Celtic bracelets, Arab chains. Look at these statuettes, Beautrelet, at this Greek Venus, this Corinthian Apollo. Look at these Tanagras, Beautrelet: all the real Tanagras are here. Outside this glass case, there is not a single genuine Tanagra statuette in the whole wide world. What a delicious thing to be able to say!—Beautrelet, do you remember Thomas and his gang of church-pillagers in the South—agents of mine, by the way? Well, here is the Ambazac reliquary, the real one, Beautrelet! Do you remember the Louvre scandal, the tiara which was admitted to be false, invented and manufactured by a modern artist? Here is the tiara of Saitapharnes, the real one, Beautrelet! Look, Beautrelet, look with all your eyes: here is the marvel of marvels, the supreme masterpiece, the work of no mortal brain; here is Leonardo’s Gioconda, the real one! Kneel, Beautrelet, kneel; all womankind stands before you in this picture.”

There was a long silence between them. Below, the sound of blows drew nearer. Two or three doors, no more, separated them from Ganimard. In the offing, they saw the black back of the torpedo-boat and the fishing-smacks cruising to and fro.

The boy asked:

“And the treasure?”

“Ah, my little man, that’s what interests you most! None of those masterpieces of human art can compete with the contemplation of the treasure as a matter of curiosity, eh?—And the whole crowd will be like you!—Come, you shall be satisfied.”

He stamped his foot, and, in so doing, made one of the discs composing the floor-pattern turn right over. Then, lifting it as though it were the lid of a box, he uncovered a sort of large round bowl, dug in the thickness of the rock. It was empty.

A little farther, he went through the same performance. Another large bowl appeared. It was also empty.

He did this three times over again. The three other bowls were empty.

“Eh,” grinned Lupin. “What a disappointment! Under Louis XI., under Henry IV., under Richelieu, the five bowls were full. But think of Louis XIV., the folly of Versailles, the wars, the great disasters of the reign! And think of Louis XV., the spendthrift king, with his Pompadour and his Du Barry! How they must have drawn on the treasure in those days! With what thieving claws they must have scratched at the stone. You see, there’s nothing left.”
