"They may have broken down in their car; and learning they were close to this house have come on here to wait till repairs are made. Lots of them know Potzfeldt, I suppose, and one of these men may have been here before on business. The worst of it all is we'll have to give up our scheme of going down by way of the stairs."

They crouched down and watched as best they could, while the half-dozen men in the gray-green uniforms of German officers, and with many decorations on the breast of the martial-looking commander, approached the château's front door.

Already lights had sprung up on the lower floor. Undoubtedly Potzfeldt had heard his unexpected guests coming, and was bestirring himself to welcome them, though inwardly raving over having his rest so frequently disturbed.

He met them at the door, and there ensued more or less talking, all of it in the choicest of German. Again Jack felt sorry that his education was so incomplete that he could only guess at what most of it meant.

Still, Tom could pick up a little of what was said. There was certainly mention made of an unfortunate accident to a car, that would necessitate a delay of some hours for repairs, possibly until morning. The general did not altogether fancy sitting in the car for hours in the cool night air. Especially was this the case after he had learned that there was a house half a mile or so further on where food and drink could be obtained in plenty, if only they chose to walk that far.

All of the newcomers had by now stalked inside the house, and the coast seemed to be clear, so far as those above could see. But down below there was much hurrying to and fro, which would indicate that Potzfeldt must have aroused his retainers, and they were running up and down from wine-cellar to dining-room, bearing acceptable refreshments for the unbidden guests.

"Say, I wonder if that old stout chap could be Hindenburg himself?" Jack whispered in his chum's ear. "I noticed that Mr. Potzfeldt seemed mighty obsequious, as if he felt highly honored at having such a noble visitor, and nothing could be too good to set before him."

"Well, I wouldn't be surprised if you'd hit the nail on the head when you said that, Jack," the other told him. "He was a big, burly man, with a mighty important air about him; and he wore a mustache such as we've always seen in pictures of Hindenburg. But no matter, it doesn't concern us at all, if we can find a way to get down from here."

"Only," said Jack, whimsically, "I do hope if they've got their German appetites along, they don't clean out that pantry before I get my look-in, that's all. Twenty-four hours without a single bite would be the limit for me. I don't think I'd survive the ordeal. Now what, Tom?"

Tom was looking out again.
