So they went and rummaged as they liked. Quiet reigned in the corridors, and they saw hardly a lackey in the distance. They climbed up a staircase and followed the passage till they came to the arches, showing that they were in the part of the Schloss which dated from the time of John the Headstrong and Heinrich the Confessor, as Klaus Heinrich knew and explained. They came to the hall of the pillars, and Klaus Heinrich there whistled several notes close after each other, for the first were still sounding when the last came, and so a clear chord rang under the vaulted ceiling. They scrambled groping and often on hands and knees up the stone winding staircase which opened behind one of the heavy doors, and reached the room with the wooden ceiling, in which there were several strange objects. There were some broken muskets of clumsy size with thickly rusted locks, which had been too bad for the museum, and a discarded throne with torn red velvet cushions, short wide-splayed lion-legs, and cupids hovering over the chair-back, bearing a crown. Then there was a wicked-looking, dusty, cage-like, and horribly interesting thing, which intrigued them much and long. If they were not quite mistaken, it was a rat-trap, for they could see the iron spike to put the bacon on, and it was dreadful to think how the trap-door must fall down behind the great beast.... Yes, this took time, and when they stood up after examining the rat-trap their faces were hot, and their clothes stiff with rust and dust. Klaus Heinrich brushed them both down, but that did not do much good, for his hands were as filthy as his clothes. And suddenly they saw that dusk had begun to fall. They must return quickly, Ditlinde insisted anxiously on that; it was too late to go any farther. "That's an awful pity," said Klaus Heinrich. "Who knows what else we mightn't have found, and when we shall get another chance of rummaging, Ditlinde!" But he followed his sister and they hurried back down the turret-stairs, crossed the hall of the pillars, and came out into the arcade, intending to hurry home hand-in-hand. Thus they wandered on for a time; but Klaus Heinrich shook his head, for it seemed to him that this was not the way he had come. They went still farther; but several signs told them that they had mistaken their direction. This stone seat with the griffin-heads was not standing here before. That pointed window looked to the west over the low-lying quarter of the town and not over the inner courtyard with the rose-bush. They were going wrong, it was no use denying it; perhaps they had left the hall of the pillars by a wrong exit--anyhow they had absolutely lost their way.
