Towards tea-time the sky suddenly darkened. The girls went to the window. Yamen was with them, and she looked out too.
“A storm is coming,” she said, pointing to the west. “A great storm. You must not be frightened, little ones. Sometimes, when the weather has been hot, the big clouds blow up, and the lighning tears the sky in two, whilst the thunder roars and echoes round.”
“We are not afraid of storms, Yamen,” said Nora. “It ought to be a wonderful sight, a storm in the Killimooin Mountains!”
The sky grew so black that the girls could not see to read. Great clouds began to roll round the mountain itself, and soon the castle was completely swallowed up in the thick, swirling mists. Thunder rumbled in the distance. The little children in the nurseries of the castle began to cry.
“There’s the lighning!” said Nora, as a vivid flash appeared, and everything was lighted up clearly for an instant. “Oh — what thunder! I’ve never heard anything like it!”
Killimooin seemed to be in the midst of the storm. Thunder cracked round the castle, and the lightning shivered the sky to pieces. It was as dark as night between the flashes.
“Although the two girls were not afraid of storms, they were awed by this one. The noise was so terrific and the lightning was so grand.
Then the rain came. Rain? It sounded more like a waterfall pouring down on the castle, lashing against the windows, forming itself into rivulets that rushed down the hillside at top speed. Never in their lives had the two girls seen or heard such rain. It almost drowned the thunder that still rolled around!
“Well, it’s a mercy the boys are not out in this, but are somewhere in a cave,” said Nora, trying to be cheerful.
But the boys were not in a cave! No, they were making their way towards the river where it entered the Secret Forest! They were almost there, and could see its shining waters. They were glad, because now they felt that they knew their way. They had only to follow the river’s course backwards to the mountain, and climb up beside it as it flowed down through the heart of the hill!
Then the sky darkened, and the storm blew up. First, it was very still, and Ranni glanced uneasily at the sky. He knew the Baronian storms! They were as grand as the mountains themselves!
The storm broke, just as the little party reached the river and began to follow its swift course backwards to the mountain. Thunder cracked above their heads, and lightning split the darkened sky.
“We had better shelter,” said Ranni, and looked about for somewhere to go. He did not want to stand under the trees in case they were struck by lightning. There were some thickly-growing bushes nearby with enormous flat leaves. The rain fell off the leaves as if they were umbrellas.
“We’ll crawl under these bushes,” said Ranni. “We can draw our cloaks over our heads. The rain will not soak through the fur lining.”
But it did! It soaked through everything, and once again the company were wet! The boys hated the fierceness of this rainstorm. The drops pelted down, stinging them, slashing them, soaking through the bushes, their fur-lined cloaks, their clothes, and everything.
“What a storm!” said Paul. “It is the worst I ever remember in Baronia. I don’t like it, Pilescu.”
Pilescu pulled the small boy to him and covered him with his great arms. “You are safe with Pilescu,” he said. “Not even the worst storm can harm you now!”
For two hours the rain poured down, never-ending. Jack was astonished to think that so much water could be held by clouds! It was as if someone up in the sky was emptying whole seas of water down on to the earth.
At last a break came in the clouds and a bit of brilliant blue sky showed through. The thunder died away. The lightning no longer flashed. The clouds thinned rapidly, and the rain stopped. The boys heaved sighs of relief. They were wet, cold and hungry. Ranni felt about in his big pockets and brought out some chocolate. It was very welcome.
“Now we must get on,” he said. “If the sun comes out strongly, before it sets, we shall soon be dry again. We have a long climb ahead before we reach the place where the river gushes forth from the mountain. Shall I carry you for a while, little lord?”
“Certainly not,” said Paul. “I can walk as well as Mike and Jack!”
But after three hours of hard walking the little prince was only too glad to be hoisted on to Pilescu’s broad back! They made their way slowly on and up, the noise of the water always in their ears. They saw no sign of the robbers at all, though they kept a sharp look-out for them.
When evening began to fall they reached the place where the river flowed out of the mountain-side, rushing and roaring as if in pleasure to see the sun. They sat by the water and rested. They were all tired now.
“Well, we must begin our watery climb now,” said Ranni, at last. “It will take us some hours to follow the river up to where it falls into the cave above. The way will be steep and often dangerous. Paul, I am going to tie you to me, for if you fall into the river, I cannot save you. You will be whirled away from me in an instant.”
“Well, tie Mike and Jack to Pilescu, then,” said Paul. “I don’t want to be the only one.”
In the end, all five were roped together, so that if one fell, the others might pull him up again to safety. Then the five of them entered the cavernous hole in Killimooin Mountain, and prepared to climb up beside the rushing torrent.
There was a narrow ledge, as Ranni had guessed. It was wet and slippery, and sometimes so narrow that it seemed impossible to walk on it. But by finding firm hand-holds in the rocky wall of the tunnel, the climbers managed to make their way steadily upwards.
Once Paul slipped and fell. He almost jerked Ranni off his feet, too. The boy half fell into the rushing water, but Ranni caught hold of the rope and tightened it quickly. The boy was pulled back to the ledge, and knelt there, gasping with fright.
“You are safe, little Paul. Do not be afraid,” said Ranni, comfortingly, shouting above the rushing of the water.
“I’m not afraid!” yelled Paul, and got to his feet at once. He had had a bad scare, but he would not show it. Ranni felt proud of the little prince.
They toiled upwards, not saying a word, because it was soon too much effort to shout to make themselves heard above the noise of the river. It seemed as if they had been climbing up the narrow ledge for hours, with Ranni’s torch showing the way at the front, and Pilescu’s at the back, when the five saw something that startled them exceedingly.
The light from Ranni’s torch fell on something swirling down the torrent! In surprise Ranni kept his torch pointed towards it — and the little company saw that it was a raft, on which were five or six of the small, wiry robbers, bobbing rapidly downwards to the Secret Forest!
The robbers saw them too, and uttered loud cries of amazement. In half a minute they were swept away down the river, out of sight, lost in the long black tunnel through which the water rushed downwards.
“They saw us!” yelled Jack. “Does it matter, do you think? Will they come after us?”
Ranni and Pilescu stopped to consider the matter. They thought it was possible that the robbers would turn back and pursue them. It would be easy to swing their raft against the side and leap out. They could drag their raft up behind them, as they apparently did each time they climbed up to the temple-cave.
