"Shucks!" mocked Alec, disdainfully. "What good are locks and bars and bolts when they say a ghost can ooze itself in through a keyhole even? But then don't get an idea in your head, Billy, we're going to be bothered by anything except rats. That's the only kind of spooks you'll find in such a place as this. And after we've had our supper I hope you'll all accompany me while I take some views of the interior, because several of the rooms are going to make dandy pictures."

So supper was cooked after their customary camp style, only in this instance, while the scouts had a roof overhead, and stout stone walls surrounding them, they missed the whispering of the treetops, as well as the star-studded sky.

Afterwards they gladly helped the aspiring photographer while he made good use of his flashlight apparatus. Alec chose certain apartments in which he fancied his wealthy and eccentric aunt would be most interested. He also declared himself satisfied in the end that he had succeeded in getting some views that ought to turn out "gilt-edged."

The mansion was unfurnished, so that they had no chance of finding sleeping quarters or beds of any kind above. Whoever now owned the place had removed all such articles long since, possibly to prevent tramps from finding an inducement to lodge in the deserted and lonely, castle.

However, this was nothing serious to fellows who had camped many a time among the rocks, where they were even debarred from having hemlock browse for a soft mattress.

"We'll try the floor to-night, boys," said Hugh, as he started to spread his blanket out in regulation style. "If it proves to be too hard for us, perhaps we can put in the second night outdoors somewhere. That will depend on the weather, for we have no tent to keep the rain or snow off, you remember."

The others hastened to copy his example, for they were all fairly sleepy. Billy told himself that he would very likely lie awake all nightlong, because he felt sure something strange was bound to happen to them. He was shrewd enough to arrange his blanket bed directly in the middle, so that he had a pair of chums on either side of him. If the others noticed this sign of weakness they kindly overlooked it. Perhaps, to tell the truth about it, Monkey Stallings and Arthur Cameron were themselves not entirely free from uneasiness, and deep down in their hearts wished the night well over with.

Hugh happened to awaken some time afterwards, and as the flames lazily lighted up the big room occasionally, he lay there watching them play upon the wall. So he allowed himself to figure what strange scenes these same rooms must have witnessed in those bygone days when the old judge and his young prisoner wife occupied the monstrosity of an imitation feudal castle.

When Hugh was about to turn over and compose himself to sleep, he heard a peculiar sound that caused his heart to beat much more rapidly than its wont. He suddenly sat up and listened again.
