The Curious Cases of Detective Richard Duvall (All 3 Books in One Volume). Frederic Arnold Kummer
It terminated at a small, third-class hotel in the older part of the city, where he went in, entered the café, and selecting a table in a dim corner, ordered breakfast.
Duvall, feeling safe in leaving him, at once sought a telephone and proceeded to call up Dufrenne at the Hotel Metropole.
The latter, meanwhile, had turned from the railway station, and was proceeding up the street at a leisurely pace, when a young man approached him from behind, and touched him lightly on the shoulder. "Monsieur Dufrenne?" he inquired, smiling.
The curio dealer glanced at the man who had accosted him, and an answering smile lit up his face. "Oh, Lablanche, glad to see you," he said. "I did not know you were on this case."
"Monsieur Lefevre sent me from Paris last night. We are expecting news at any moment. Monsieur Duvall is with you, I observe."
"Yes. He is following the man from London. He will telephone me, as soon as he learns his destination."
The man whom Dufrenne had addressed as Lablanche, looked grave. "This affair has, we believe, been engineered by a physician here—Dr. Hartmann—you have heard of him, of course."
Dufrenne turned to his companion. "Hartmann—the man of the stolen war plans. Mon Dieu! Why did I not think of him before?" He seemed deeply chagrined. "Of course—of course—that explains everything."
"Where is Monsieur Duvall to communicate with you?" Dufrenne's companion asked. His voice held a note of brisk authority.
"At the Hotel Metropole. I shall take a room there at once."
"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 10
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.
During the drive, he began to formulate a plan, daring in its conception, extremely dangerous in its execution, yet one which, if carried out with courage and determination, promised success. He was perfecting in his mind the details of this plan when the carriage turned into the driveway at Dr. Hartmann's.
So occupied had he become with his thoughts that he failed to observe the figure of Grace, standing behind the maid in the open doorway; she disappeared into the reception-room before he had alighted from the cab. He went up to the servant, assumed an air of dignified assurance, and announced that he wished to see Dr. Hartmann at once.
The maid ushered him in, glanced into the parlor, observed Grace sitting there, apparently reading, and then throwing open the door to the left which gave admittance to the doctor's office, bade Duvall enter. The latter stepped in at once, without looking into the room across the hall. Had he done so, he would have observed his wife, whom he fully supposed to be quietly waiting for him in Paris, rise from her chair with a frightened face and start impulsively toward him.
For a moment Grace was on the point of calling out—she wanted to let Richard know that she was there. She wanted to see him—to talk to him, to realize the happiness of being once again in his presence. It had been, since their parting the day before, her constant thought. Then she suddenly realized that Monsieur Lefevre had warned her not to appear to recognize her husband, should she meet him in the course of her adventures. The thought checked her—she paused at the door of the reception-room and glanced down the hall.
The servant who had admitted Duvall had disappeared toward the rear of the house. Everything about her seemed quiet. She started across the hall, determined to enter the room into which Richard had just vanished, when she heard the sound of rapid footsteps approaching her. With a start she turned and again entered the parlor, assuming a careless manner she by no means felt.
She had scarcely seated herself in the chair by the fire, and opened her book, when she saw Dr. Hartmann appear in the hall and enter the door which led to the outer office.
Grace was undecided as to what she should do next. Her safest course, she ultimately concluded, was to do nothing. She remained quietly in her seat, pretending to read her book, but all the while watching, with anxious eyes, the door on the other side of the hall.
Richard Duvall, meanwhile, had entered the waiting room, his mind fully made up as to the course he was about to pursue. During the few moments which intervened, until the doctor's arrival, he looked keenly about the room, examining it in detail, fixing its entrances and exits firmly in his mind, so as to be prepared for any emergency which might arise.
The room was a large one. Along the side facing the entrance door, as well as that which fronted on the park, were big curtained windows, set in deep recesses, and between them, cases of books. At the far end of the room, toward the rear of the house, was another door. Duvall stole over to it, listened carefully, then slowly opened it and looked within. The room proved to be the doctor's private office, and he saw at once that it was built in a sort of ell, and could not be entered except through the room in which he stood. There was a door, it is true, in the right-hand wall, which had once given entrance to the hall, but against this a heavy instrument case, with glass doors, now stood.
Duvall withdrew his head and shoulders from the doorway, nodding to himself in a satisfied way, then noiselessly closed the door and returned to the center of the room.
In a moment Dr. Hartmann came in, glancing at him sharply. "Good-morning, sir," he remarked, in French. "You wish to see me?"
The detective took a card-case from his pocket and tendered the doctor a card. It was one of many which he carried for such emergencies, and bore the
