“What’s the game, Tom? They went to a good deal of preliminary trouble—I mean kidnapping me for you.” “Admittedly on their part, that was a mistake,” said Tom. “It was me they were after all the time, only you happened to leave the laboratory first and they pounced on you. Then came the explosion. Whether that was set to go off and destroy my laboratory after I was supposed to be out of it or whether they really wanted to do me up, I don’t know. But they’ve got both of us now.” “Any idea who they may be, Tom—I mean these men?” “They might be the Hussy and Kilborn crowd.” “You mean that bunch of the _Red Arrow_ who tried to stop us from circling the globe?” “That’s who I mean. However, it’s only a guess. It may turn out to be an entirely different gang. But now that we have a little time to ourselves, let’s look around and see what the chances are for getting away.” It was dusk, but by the last rays of the setting sun which shone through the window, the young men began a tour of the apartment, seeking any possible means of exit. Naturally, they first gave their attention to the window and door. As stated before, the former was screened not only with a wire mesh, but also with strong iron bars. A search through the pockets of Tom and Ned revealed, in the way of tools, only two knives. Tom’s knife contained a small screw driver, and at first he thought he might be able to loosen the fastenings of the screen and window bars. But it did not take long to demonstrate that a much more powerful instrument would be needed for this work. “Anyhow, if we did get the bars off we’d have a big drop to the ground,” said Ned. “We’re higher up than I thought.” “We could improvise a rope from the bed-clothes,” suggested Tom, indicating them. “That would be the easiest part of it. But those bars were put there to stay.” “Maybe we can whittle away the wood enough to loosen the screws,” suggested Ned. They tried this, but the space to work in was cramped, the wood was tough, and when Ned broke the largest blade of his knife and cut his hand rather severely in so doing, Tom insisted that they give up this attempt. “Let’s try the door,” he said. It was now dark in the room, but both young men had matches, Tom’s being in a waterproof case which had kept dry during his sudden bath, and with these they made as good an examination of the door and its frame as was possible. The lock defied picking with the poor tools at their disposal, and when this had been proved Tom said: “We can cut a hole through the door near the lock, big enough for a hand to get through, and maybe we can turn the lock that way.” “It’s worth trying,” Ned declared. “We’ll work at it in shifts.” Their captors seemed to have made up their minds to leave the prisoners alone, though voices and movements in the rooms below indicated that the three men were still on guard. Perhaps orders had come from the mysterious “Chief” not to attempt violence.
