dell and flung themselves through the gap into the beech wood. Fingers clawed, and ropes hissed like snakes, but they were through and plunging down the slope in a flurry of dead leaves.
“Stop, Sue!” yelled Colin.
He realised that their only hope of escape lay in reaching open ground and the path that led from Stormy Point to the road, where their longer legs might outdistance their pursuers’, and even that seemed a slim chance.
“Stop, Sue! We must … not go … down … any further! Find … Stormy Point … somehow!”
All the while he was looking for a recognisable landmark, since in the fear and dusk he had lost his bearings, and all he knew was that their way lay uphill and not down.
Then, through the trees, he saw what he needed. About a hundred feet above them and to their right a tooth-shaped boulder stood against the sky: its distinctive shape had caught his eye when they had walked past it along a track coming from Stormy Point!
“That boulder! Make for that boulder!”
Susan looked where he was pointing, and nodded.
They began to flounder up the hill, groping for firm ground with hands and feet beneath the knee-high sea of dead leaves. Their plunge had taken them diagonally across the slope, and their upward path led away from the dell, otherwise they would not have survived.
The others had come skimming lightly down over the surface of the leaves, and had found it difficult to check their speed when they saw the quick change of direction. Now they scurried across to intercept the children, bending low over the ground as they ran.
Slowly Colin and Susan gained height until they were at the same level as the pursuit, then above it, and the danger of being cut off from the path was no longer with them. But their lead was a bare ten yards, and shortening rapidly, until Colin’s fingers, scrabbling beneath the leaves closed round something firm. It was a fallen branch, still bushy with twigs, and he tore it from the soil and swung it straight into the leaders, who went clamouring, head over heels, into those behind in a tangle of ropes and nets.
This gained Colin and Susan precious yards and seconds, though their flight was still nightmare: for unseen twigs rolled beneath their feet, and leaves dragged leadenly about their knees. But at last they pulled themselves on to the path.
“Come on, Sue!” Colin gasped. “Run for it! They’re … not far … behind … now!”
The children drew energy from their fear. Above their heads a bird cried harshly three times, and at once the air was filled with the beating of a gong. The sound seemed to come from a distance, yet it was all about them, in the air and under the ground.
Then they ran clear of the trees and on to Stormy Point. But their relief was short-lived; for whereas till that moment they had been fleeing from twenty or so, they were now confronted with several hundred of the creatures as they came out of Devil’s Grave like ants from a nest.
Colin and Susan halted: gone was their last hope of reaching the road: the way was blocked to front and rear: on their left was the grim beech wood: to the right an almost sheer slope dropped between pines into a valley. But at least there was no known danger there, so the children turned their faces that way and fled, stumbling and slithering down a sandy path, till at last they landed at the bottom – only to splash knee-deep in the mud and leaf-mould of the swamp that sprawled unseen down the opposite wall of the valley and out across the floor.
They lurched forward a few paces, spurred on by the sound of what was following all too close behind, but then Susan staggered and collapsed against a fallen tree.
“I can’t go on!” she sobbed. “My legs won’t move.”
“Oh yes you can! Only a few more yards!”
Colin had spotted a huge boulder sticking out of the swamp a little way up the hill from where they were, and, if only they could reach it, it would offer more protection than their present position, which could hardly be worse. He grabbed his sister’s arm and dragged her through the mud to the base of the rock.
“Now climb!”
And, while Susan hauled herself up to the flat summit, Colin put his back to the rock, like a fox at bay turning to face the hunt.
The edge of the swamp was a mass of bodies. The rising moon shone on their leathery hides and was reflected in their eyes. Colin could see white shapes spreading out on either side to encircle the rock; they were in no hurry now, for they knew that escape was impossible.
Colin climbed after his sister. He ached in every muscle and was trembling with fatigue.
When the circle was complete the creatures began to advance across the swamp, moving easily over the mire on their splayed feet. Ever closer they came, till the rock was surrounded.
From all sides at once the ropes came snaking through the air, as soft as silk, as strong as iron, and clung to the children as though coated with glue; so that in no time at all Colin and Susan fell helpless beneath the sticky coils, and over them swarmed the mob, pinching and poking, and binding and trussing, until the children lay with only their heads exposed, like two cocoons upon the rock.
But as they were being hoisted on to bony shoulders it seemed as though a miracle happened. There was a flash, and the whole rock was lapped about by a lake of blue fire. The children could feel no heat, but their captors fell, hissing and spitting, into the swamp, and the ropes charred and crumbled into ash, while pandemonium broke loose through all the assembly.
Then, from the darkness above, a voice rang out.
“Since when have men-children grown so mighty that you must needs meet two with hundreds? Run, maggot-breed of Ymir, ere I lose my patience!”
The crowd had fallen silent at the first sound of that voice, and now it drew back slowly, snarling and blinking in the blue light, wavered, turned, and fled. The dazed children listened to the rushing feet as though in a dream: soon there was only the rattle of stones on the opposite slope; then nothing. The cold flames about the rock flickered and died. The moon shone peacefully upon the quiet valley.
And as their eyes grew accustomed to this paler light the children saw standing on the path beneath a cliff some way above them an old man, taller than any they had ever known, and thin. He was clad in a white robe, his hair and beard were white, and in his hand was a white staff. He was looking at Colin and Susan, and, as they sat upright, he spoke again, but this time there was no anger in his voice.
“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,
