"Now, then." He arose and looked about the room. On a table near the door were several rolls of parchment. He went over to them and lifted them. They were the plans of the torpedo. With a sigh of relief he straightened them and folding the sheets into two small but bulky packages, put them into his pockets. Evidently the apartment had been thoroughly ransacked by Takakika. Drawers were opened, bags turned inside out, the bed torn apart, and the mattress ripped. But where was the control? Armitage felt about the Jap's clothing and then feverishly began going over the line of search pursued by the spy. So engrossed had he been in the struggle with Takakika that he had forgotten his intention of locking the door leading from the hall. Now his unsuccessful search filled his mind. At last in a dark corner of a closet he unearthed a small square bag. He had just taken it into the room and cut it when the door opened and Koltsoff entered. For an instant he stood blinking and then his eyes travelled swiftly about the room, taking in Armitage, the bound and half conscious Japanese, and the general litter. Jack watched him closely, ready for any move he might make. The Russian's sudden appearance had startled him, but the first substantial thought that shot through his mind was that no one could possibly have been more welcome. He had failed to find the control: he had to have it. So he might as well have it out with the Prince now as any other time. If Koltsoff but knew it, he was facing a desperate man; for until he had entered and searched the rooms, Jack had harbored no doubt that possession of the control was merely a matter of overhauling the Prince's effects. Now he knew better, and for the first time he was really alarmed as to its whereabouts. He returned Koltsoff's gaze with smouldering eyes. But the Russian was very much at ease. "What is it?" he asked at length. Without waiting for Armitage to reply he walked swiftly to the desk, jerked open a panel, and placed his hand in the opening. When he withdrew it, it was empty. Jack laughed, drew from his pocket a short heavy revolver with a pearl, gold-crested handle, twirled it about by the guard, and then put it back in his pocket. "I got there first, Koltsoff," he said. Prince Koltsoff straightened and regarded Armitage warily. "What does this mean?" He nodded his head toward Takakika and started forward as for the first time he noticed that the man was a Japanese. "Ah," he said, "I see. You have foiled a spy. Ha! ha! I thank you. And now the pistol--and your manner! Ha! ha! ha! Your joke!" Armitage saw clearly that for some reason--which he believed he recognized--Koltsoff was willing that the incident, so far as Jack was concerned, should end right there. The Prince had given him his lead. He had but to follow it and clear out, with no questions asked. But that was farthest from his mind. "My joke is not clear to you, I see."
