He turned to the two men. "You do not intend to release me then?" he asked, angrily.
Hartmann laughed. "You will be quite comfortable here, my friend. I am sure that a few days of complete rest will benefit your condition greatly. I imagine your trouble is merely a temporary affliction—a loss of memory, let us say, an inability to recall your name. We'll soon have you all right again. You have only to inform me where you have placed the snuff box which you stole from my messenger this morning, and I shall know that a complete cure has been effected. If your friends are alarmed about you, it will be quite sufficient to tell them that you are in my care. Mr. Phelps, for instance, has complete confidence in my ability. I will make it a point to explain matters to him at once. Just a trifling ailment, a disordered condition of the brain cells. A week should set you right again. If there is anything you wish, the attendants will get it for you. Your clothes will be sent up from the hotel in the morning. Make yourself quite at home, I beg of you."
He turned away, with a sardonic smile, and Duvall heard the key turn in the door as it closed. He glanced at the barred windows, the door, half-open, leading to the bathroom, and realized that there was not the slightest hope of escape. Dr. Hartmann evidently intended to keep him a prisoner until he disclosed the whereabouts of the snuff box. He smiled grimly as he threw himself upon the bed. It seemed likely that his stay would be a long one.
After a time he began to think of Grace. How cleverly she had carried out her part! It was clear that the doctor did not suspect her, or, if he did, was unable to see where his suspicions led. How strange it seemed to realize that she, his wife, lay somewhere under the same roof with him—possibly even in the very next room! But thirty-six hours had passed since their wedding and their sudden and unexpected parting. During that time, he had seen Grace but twice, once, at Hartmann's office, in the morning; the second time, at the Minister's that night. How he had longed to touch her hand, to put his arms about her, to feel his lips on hers. Yet as matters stood, the chances of their seeing each other in the near future seemed particularly remote. He wondered if Hartmann would keep him a prisoner in his room. The morning, of course, would tell. He switched off the lights, got into bed, and after a long time fell into a broken sleep.
CHAPTER XV
It was late in the afternoon, when Dr. Hartmann, through his man Mayer, discovered that Seltz had left London, and should have appeared at his office with the snuff box during the forenoon. A description of Seltz, together with a curious feeling of uneasiness which he felt after the departure of the man who had introduced himself as Mr. Brooks, caused him to conclude that he had been made the victim of a clever trick, and one which only his professional enthusiasm had made possible.
He at once set to work, through Mayer and his men, to locate Brooks. This was done, without difficulty, at the Hotel Metropole. While the doctor followed the latter to the Minister's, firm in his belief that he carried the snuff box with him, Mayer had arranged through certain connections with the Belgian police, to have Dufrenne arrested and placed in confinement over night on a trumped-up charge; Seltz liberated, and Lablanche held on a pretense of being concerned in the theft from the latter of a valuable package. A thorough search of Duvall's baggage—Dufrenne, it seemed, had none—disclosed nothing, except certain documents setting forth that the latter was Richard Duvall, an American citizen. It was these papers, in fact, which Duvall had shown to Mr. Phelps earlier in the day.
There was nothing to indicate to Hartmann that Duvall was acting in the interests of the French secret police, but the doctor suspected it, knowing as he did that the recovery of Monsieur de Grissac's snuff box would become at once a matter of the utmost moment to Lefevre and his men. Curiously enough, his momentary suspicions of Grace had largely disappeared. There was nothing to connect her with Duvall. He did not know that it was she who had opened the door and admitted Seltz to his house earlier in the day—he thought that Duvall had done this himself. Grace's manner, her conduct during the ride in the cab from the Minister's house, had shown him nothing. Still, he felt that she would bear watching and made his plans accordingly.
The sun was shining through the windows of Duvall's room when he awoke the next morning. For a brief space he was unable to recognize his surroundings, then the sequence of events came to him with a rush. He was conscious of a knocking at the door. He sprang up and opened it. Outside stood one of the men attendants whom he had seen the night before, with the portmanteau containing his clothes. The man placed the bag upon a chair, and opened it, then withdrew.
