“He’s blown it out and got under the bed!” said Dick. “Poor Sam! It really must be terrifying for him. Let’s go and peep into his hut.”

They went over to it and tried to see in at the window. But there was nothing to be seen. The hut was in complete darkness. Then suddenly a little flare flashed out somewhere near the floor.

“Look — there’s Sam! He’s lighting a match,” said Julian. “See — he’s peeping out from under the bed. He looks scared stiff. Let’s tap on the window and ask him if he’s all right.”

But that was quite the wrong thing to do! As soon as Julian tapped sharply on the window, Sam gave an anguished yell and retired hurriedly under the bed again, his wavering match-light going out.

“It’s come for to take me!” they heard him wailing. “It’s come for to take me! And me with my wooden leg off too.”

“We’re only frightening the poor old fellow,” said Dick. “Come on. Let’s leave him. He’ll have a fit or something if we call out to him. He honestly thinks the spook-train’s come to get him!”

They wandered round the dark yard for a few minutes, but there was nothing to find out in the darkness. No more rumbling came to their ears. The spook-train was evidently not going to run again that night.

“Let’s go back,” said Julian. “Golly, that was exciting! Honestly, my hair stood up on end when that train came puffing out of the tunnel. Where on earth did it come from? And what’s the reason for it?”

They gave it up, and began to walk back to the camp. They scrambled through the heather, tired but excited. “Shall we tell the girls we’ve seen the train?” said Dick.

“No,” said Julian. “It would only scare Anne, and George would be furious if she knew we’d gone without her. We’ll wait and see if we discover anything more before we say anything, either to the girls or to old Luffy.”

“Right,” said Dick. “You’ll hold your tongue, too, won’t you, Jock?”

“Course,” said Jock, scornfully. “Who would I tell? My stepfather? Not likely! How furious he’d be if he knew we’d all pooh-poohed his warnings and gone down to see the spook-train after all!”

He suddenly felt something warm against his legs, and gave a startled cry: “Gosh! What’s this? Get away!”

But the warm thing turned out to be Timmy, who had come to meet the three boys. He pressed against each of them in turn and whined a little.

“He says, ‘Why didn’t you take me with you?’ ” said Dick. “Sorry, old thing, but we couldn’t. George would never have spoken to us again if we’d taken you, and left her behind! How would you have liked spook-trains, Timmy? Would you have run into a corner somewhere and hidden?”

“Woof,” said Timmy, scornfully. As if he would be afraid of anything!

They reached their camping-place and began to speak in whispers. “Good-bye, Jock. Come up to-morrow if you can. Hope you don’t have that Cecil boy to cope with!”
