That last seemed to be the wrong thing to say. The conductor's eyes flashed and he shot a stern look at Dawson.

"Oh, I can, can I?" he snapped. "Very nice of you to tell me, I'm sure. But I have my orders, and I know what they are. All travel vouchers must be in order for people to travel on my train. I'll have to ask you to come along with me and see the Company Inspector, who is in the next to one car back. You can make your explanations to him. And if he says it's all right, then it'll be all right for me."

"And that will be just ducky!" Dawson growled, and got up off the seat. "Okay. If it will take a great load off your mind, my friend, then we'll go back and see the Inspector. But on second thought, let's have the Inspector come see us. What do you say, Freddy, huh?"

"Oh, come off it, Dave!" the English youth growled. "Why make a mountain of it? The chap is just doing his job. So let's go back and straighten it all out with the Inspector. Besides, a bit of a walk wouldn't do either of us any harm."

"For that reason, I agree," Dawson grunted, and stepped through the compartment door that the conductor had rolled open.

Leading the way, he headed for the end of the car, and, unlike in the vast majority of English trains, the end door and passageway that permitted travel from car to car. But just as he was stepping into the next car a figure suddenly appeared out of nowhere directly in front of him, and something blunt and hard was jammed against his chest.

"One sound, and there'll be a dead man under the wheels!" a voice hissed. "Stand right where you are!"

Dave froze stiff, and then was almost knocked off balance as Freddy Farmer came bumping into him from behind. For a split second he half expected to hear the English youth comment volubly on the situation. But he didn't hear a sound. He only felt his pal stiffen, and that was more than enough to tell him that one fake conductor had unquestionably rammed a similar blunt hard object into Freddy's back, and whispered a few words of warning, too.

For a long moment the whole world seemed to stand still for Dave. He knew that he was straining his eyes for a glimpse of the figure blocking his path, but in the bad light he could see nothing but a vague silhouette. Then suddenly he saw the figure's hand reach up and yank hard on the emergency cord. Almost instantly the speed of the train fell off as the engineer up ahead slammed on the brakes. The jolting and jarring lurched Dave forward, but he was prevented from going on his face by the blunt, hard object still digging into his chest.

"I am going to open the side door!" the voice suddenly whispered in his ear. "Get in front of me, and, when I order, jump off the train. But do not try to run away. I will have both eyes on you. And I am a perfect shot, even in the dark. You understand?"
