They had to travel over a stretch of sandy waste that ran along the beach. Back in shore were a few scattered cottages, and not yet opened for the summer, and on the ocean side was the pounding surf. The hut, as Tom recalled the directions, lay just beyond a group of stunted hemlock trees that set a little way back from the ocean, on a bluff overlooking the sea. It was not near any other building. Slowly, and avoiding going any nearer the other houses than they could help, the little party made its way. They had to depend on their own judgement now, for the minor details of the location of the hut could not be given in the letter from Russia. In fact the spies themselves, in writing to their head officers about the matter, had not described the location in detail. "That looks like it over there," said Tom at last, when they had gone about a mile and a half, and saw a lonely hut with a light burning in it. Cautiously they approached and, as they drew nearer, they saw that the light came through the window of a small hut. "Looks like the place," commented the detective. "We'll have a look," remarked Tom. He crept up so he could glance in the window, and no sooner had he peered in, than he motioned for the others to approach. Looking under a partly-drawn curtain, Mr. Damon and Mr. Trivett saw the Russian whom they sought. He was seated at a table, his head bowed on his hands, and in the room were three men. A rifle stood in one corner, near one of the guards. "They're taking no chances," whispered Mr. Damon. "What shall we do, Tom?" "It's three to three," replied the young inventor. "But if we can get him away without a fight, so much the better. I think I have it. I'll go up to the door, knock and make quite a racket, and demand admittance in the name of the Czar. That will startle them, and they may all three rush to answer. Mr. Damon, you and the detective will stay by the window. As soon as you see the men rush for the door, smash in the window with a piece of driftwood and call to Mr. Petrofsky to jump out that way. Then you can run with him toward the airship, and I'll follow. It may work." "I don't see why it wouldn't," declared the detective. "Go ahead, Tom. We're ready." Looking in once more, to make sure that the guards were not aware of the presence of the rescuing party, Tom went to the front door of the hut. It was a small building, evidently one used by fishermen. Tom knocked loudly on the portal, at the same time crying out in a voice that he strove to make as deep and menacing as possible: "Open! Open in the name of the Czar!" Looking through the window, ready to act on the instant, Mr. Damon and the detective saw the three guards spring to their feet. One remained near Mr. Petrofsky, who also leaped up. "Now!" called the detective to his companion. "Smash the window!"
