One thing alone pleased him: Daubrecq had not penetrated his disguise. Daubrecq believed him to be in the employ of the police. Neither Daubrecq nor the police, therefore, suspected the intrusion of a third thief in the business. This was his one and only trump, a trump that gave him a liberty of action to which he attached the greatest importance.

Without further delay, he opened the letter which Daubrecq had handed him for the secretary-general of police. It contained these few lines:

"Within reach of your hand, my dear Prasville, within reach of your hand! You touched it! A little more and the trick was done... But you're too big a fool. And to think that they couldn't hit upon any one better than you to make me bite the dust. Poor old France! "Good-bye, Prasville. But, if I catch you in the act, it will be a bad lookout for you: my maxim is to shoot at sight.

"DAUBRECQ"

"Within reach of your hand," repeated Lupin, after reading the note. "And to think that the rogue may be writing the truth! The most elementary hiding-places are the safest. We must look into this, all the same. And, also, we must find out why Daubrecq is the object of such strict supervision and obtain a few particulars about the fellow generally."

The information supplied to Lupin by a private inquiry-office consisted of the following details:

"ALEXIS DAUBRECQ, deputy of the Bouches-du- Rh6ne for the past two years; sits among the independent members. Political opinions not very clearly defined, but electoral position exceedingly strong, because of the enormous sums which he spends in nursing his constituency. No private income. Nevertheless, has a house in Paris, a villa at Enghien and another at Nice and loses heavily at play, though no one knows where the money comes from. Has great influence and obtains all he wants without making up to ministers or, apparently, having either friends or connections in political circles."

"That's a trade docket," said Lupin to himself. "What I want is a domestic docket, a police docket, which will tell me about the gentleman's private life and enable me to work more easily in this darkness and to know if I'm not getting myself into a tangle by bothering about the Daubrecq bird. And time's getting short, hang it!"

One of the residences which Lupin occupied at that period and which he used oftener than any of the others was in the Rue Chateaubriand, near the Arc de l'Etoile. He was known there by the name of Michel Beaumont. He had a snug flat here and was looked after by a manservant, Achille, who was utterly devoted to his interests and whose chief duty was to receive and repeat the telephone-messages addressed to Lupin by his followers.

Lupin, on returning home, learnt, with great astonishment, that a woman had been waiting to see him for over an hour:

"What! Why, no one ever comes to see me here! Is she young?"

"No... I don't think so."

"You don't think so!"

"She's wearing a lace shawl over her head, instead of a hat, and you can't see her face... She's more like a clerk... or a woman employed in a shop. She's not well-dressed ..."
