"Good. I must leave you for a short time. Await news from me at the hotel. I shall, I hope, be able to inform you, within half an hour, whether our suspicions regarding Dr. Hartmann are correct or not. If they are, you will of course advise Monsieur Duvall accordingly. Above all things, the delivery of the snuff box to Hartmann must be prevented. On that point the Prefect was emphatic." The young man turned into a cross street as he concluded and was swallowed up in the crowd.
Dufrenne, after securing his room at the Hotel Metropole, sat down to wait. He did not have to wait long. The young man, Lablanche, joined him in a short time. "We have just learned," he said, gravely, "that our suspicions are entirely correct. Dr. Hartmann is responsible for the theft of the snuff box, and is momentarily expecting the man who is to deliver it to him."
Dufrenne looked grave. "Duvall should know this without delay," he said.
He had no more than spoken, when the telephone bell in his room rang. He hastened to reply and found Duvall at the other end of the wire. "Come to the Hotel Universelle," the latter said, laconically. "Hurry. I will wait for you."
Dufrenne communicated the message to Lablanche. The latter nodded. "Good!" he said. "Give Monsieur Duvall the information you have, and above all, impress upon him the necessity of acting immediately. There is no time for delay. I will follow at once, with another of our men."
The curio dealer found Duvall pacing anxiously up and down the hotel corridor, pretending to be searching a railway time-table. He nodded imperceptibly toward the café as Dufrenne entered, then turned and went out into the street. The old man followed him—in a few moments they were conversing rapidly in the doorway of a near-by shop.
Dufrenne had but a few words to say, but they were sufficient to show Duvall the extreme gravity of the situation. He stood for several moments, considering the best way by which the delivery of the stolen snuff box to Dr. Hartmann might be prevented. Then he signaled a cab which he saw approaching. "Seltz is breakfasting—inside," he said quickly to Dufrenne. "Don't let him out of your sight. I am going to see Dr. Hartmann." He sprang into the cab, gave the doctor's name to the cabman, and in a moment was being driven rapidly up the street, leaving the little old Frenchman standing blinking with astonishment on the sidewalk.
CHAPTER X
When Richard Duvall left the Hotel Universelle, en route to the office of Dr. Hartmann, he had no definite idea of just what he intended to do on reaching there. One thought was uppermost in his mind—he must prevent, in some way, and at any cost, the delivery of the snuff box to Hartmann, and since to follow Seltz to the latter's office would avail him nothing, he decided to precede him there.
