He was bent over, as if he were searching for something. He felt in the dust with his fingers and several times he threw something into a cardboard box that he carried in his left hand. Afterward he obliterated the traces of his footsteps, as well as the footprints left by Lupin and the blonde lady, and he was about to leave the cellar by the same way as he had entered, when he uttered a harsh cry and fell to the ground. Sholmes had leaped upon him. It was the work of a moment, and in the simplest manner in the world the man found himself stretched on the ground, bound and handcuffed. The Englishman leaned over him and said:
“Have you anything to say?... To tell what you know?”
The man replied by such an ironical smile that Sholmes realized the futility of questioning him. So he contented himself by exploring the pockets of his captive, but he found only a bunch of keys, a handkerchief and the small cardboard box which contained a dozen garnets similar to those which Sholmes had found.
Then what was he to do with the man? Wait until his friends came to his help and deliver all of them to the police? What good would that do? What advantage would that give him over Lupin?
He hesitated; but an examination of the box decided the question. The box bore this name and address: “Leonard, jeweler, rue de la Paix.”
He resolved to abandon the man to his fate. He locked the cellar and left the house. At a branch postoffice he sent a telegram to Monsieur Destange, saying that he could not come that day. Then he went to see the jeweler and, handing him the garnets, said:
“Madame sent me with these stones. She wishes to have them reset.”
Sholmes had struck the right key. The jeweler replied:
“Certainly; the lady telephoned to me. She said she would be here to-day.”
Sholmes established himself on the sidewalk to wait for the lady, but it was five o’clock when he saw a heavily-veiled lady approach and enter the store. Through the window he saw her place on the counter a piece of antique jewelry set with garnets.
