“Come quickly, children, lest there be worse than svarts abroad; for indeed I smell much evil in the night. Come, you need not fear me.”

He smiled and stretched out his hand. Colin and Susan climbed down from the rock and squelched their way up to join him. They were shivering in spite of their coats and recent exertions.

“Stay close to me. Your troubles are over, though I fear it may be only for this night, but we must take no risks.”

And he touched the cliff with his staff. There was a hollow rumble, and a crack appeared in the rock, through which a slender ray of light shone. The crack widened to reveal a tunnel leading down into the earth: it was lit by a soft light, much the same as that which had scattered the mob in the swamp.

The old man herded Colin and Susan into the tunnel, and, as soon as they were past the threshold, the opening closed behind them, shutting out the night and its fears.

The tunnel was quite short, and soon they came to a door. The children stood aside while the old man fumbled with the lock.

“Where High Magic fails, oak and iron may yet prevail,” he said. “Ah! That has it! Now enter, and be refreshed.”

CHAPTER 4

The Fundindelve

They were in a cave, sparsely but comfortably furnished. There was a long wooden table in the centre, and a few carved chairs, and in one corner lay a pile of animal skins. Through the middle of the cave a stream of water babbled in the channel it had cut in the sandstone floor, and as it disappeared under the cave wall it formed a pool, into which the old man dipped two bronze cups, and offered them to Colin and Susan.
