'Get help,' Marjorie heard in faint accents. It was Alan's voice which recalled the shaft to her mind, and sent a thrill of terror through her. With scarcely power to reply, she had to pull herself together before she could summon up resolution to move. The bottom of the steps was not far off; she had only to turn round to mount them again, and once in the open air she was safe. How she stumbled up she never knew; but as soon as the evening air blew in her face she felt as if a load had been lifted from her heart. Ordering Bootles to keep guard, she flew up the path to the cliff, reproaching herself for her long delay there that afternoon. It would take some time to reach home, and then she must find her father, and get men and a rope. She did not know if Alan were hurt; but, in any case, his position was terrible. How had he got there? Was this also the work of Thomas? Tears were streaming from her eyes as she reached the cliff, and ran along the path to the entrance of the Wilderness. The sun had set, but the sky was still glowing, tinting with its warm colours the long, level clouds. The foreign vessel had disappeared, and as she flew along the cliff-path, she glanced hastily towards the spot where she had last seen it. Suddenly the heavy boom of a gun rent the air. Frightened at the sound, she paused a moment, and saw the white smoke curling slowly away into the evening haze, as the dark hull of a gunboat came into sight rounding the rocky promontory.

There was no time, however, to think what it all meant. It was wrong to have delayed even for an instant. Alan must be rescued before he went mad with the horrors of that shaft—that dreadful darkness! Through the Wilderness she ran at the top of her speed, and she was flying across the lawn when she almost ran into Miss Leigh by a sudden encounter round the shrubbery walk.

'Where have you been?' cried the governess, angry and excited at the absence of her pupil from the schoolroom tea, and still more at her reckless manner of running. 'You might have hurt me very seriously, Marjorie. How dare you——

But Marjorie, with a wave of her hand, had gone. There was no time for reproaches; they could very well keep for a more convenient season. Colonel De Bohun was in his dressing-room, preparing for dinner, when she rushed in without even a preliminary knock, and poured out her story with an urgent plea for haste. He quickly resumed his coat, and Marjorie had the satisfaction of seeing him take the work of rescue in hand at once. A couple of grooms were soon following them across the lawn, Marjorie leading, and as they went Miss Leigh wondered what new mischief the children had been up to.

The rescue party had not gone far before they met Estelle's nurse looking anxious and 'flustered.' No one could reply to her question concerning the little girl, but Colonel De Bohun sent her on to Miss Leigh. It was possible the child might have remained in the schoolroom, and had tea with Georgie. Marjorie knew better. The Colonel wondered at her sober face and her silence. He had no suspicion how wrong things were.

The Smuggler's Hole and the steps to the caves were a revelation to him. He looked grave when he found the entrance had been discovered. Both entrances had been carefully blocked up for many years, and he hoped the secret of their existence had been forgotten. He had not explored that part of Sir Leopold Coke's property since he was a young man, and he was not pleased to find that his children had shown more inquisitive interest in these dangerous places. There was no time for asking how they made their discoveries. Their energies must be devoted to the rescue of Alan. Alan, they found, when they let a rope down, weak and shaken as he was, could yet tie the rope round his waist, and steady himself as he was drawn up the shaft. He got better as soon as he began to walk, but the Colonel thought it best to put off all questions till the morning.

Bootles, after Alan's rescue, left the passage most unwillingly. His behaviour was inexplicable. He kept running backwards and forwards in the strangest manner. Marjorie wondered what was the matter with him, and the Colonel impatiently called him to heel.

'One would imagine something was wrong,' he exclaimed, annoyed by the dog's whines.

Marjorie related what had happened in the cave.

Scarcely had she spoken when James, Lady Coke's butler, stepped out of the shrubbery path—

'My lady has sent me for Lady Estelle, sir,' he said.

CHAPTER IX.

The shadows of evening were deepening into night before any alarm about Estelle had been felt at the Moat House. The weather being fine and clear, it was scarcely dark even at eight o'clock. The moon, now just past the full, almost turned night into day. Lady Coke had felt no uneasiness, therefore, when seven o'clock came. She imagined Estelle had been invited to spend the evening at Begbie Hall. Hitherto, however, whenever the cousins wanted her to remain, a message had been sent, in order to spare Aunt Betty any anxiety. But no such message had been received, and the clock having struck eight, then nine, without the little girl appearing, she grew anxious. Mademoiselle Vadevant was also becoming fidgety, though she strove to hide it.

'It is time for Estelle to be in bed,' remarked Lady Coke, at last. 'I am surprised that Mrs. De Bohun has kept her so late. Has Nurse gone for her?'

'Oui, madame; more than an hour ago.'

'Nine o'clock is very late for young children to be up. Will you kindly ring the bell? I will send James to bring her back without further delay.'

Mademoiselle offered to go herself, but Lady Coke insisted on dispatching James. He was her factotum, in whom she had greater faith than in any member of her household. His calm manner, which nobody had ever seen ruffled, suited her and she felt quite safe when a matter was in his hands. If Estelle needed any protection—which was not likely in their own grounds—he would be the right person to send. Having given her orders, Lady Coke felt more comfortable, each moment expecting to hear Estelle's merry voice. She sat listening unconsciously. Time, however, slipped on without bringing either James or Nurse. When, finally, ten o'clock struck, she stood up, pale but determined.

'Mademoiselle,' she said, her voice as low as ever, though her anxiety could be detected in its quiver, 'will you please send me my maid, with my garden-hat and cloak? I am going to Begbie Hall myself. You will kindly accompany me. Something must be strangely wrong.'

At that moment the sound of a man's step on the gravel under the windows made her pause, listening eagerly for the child's light tread. The steps came up the verandah, and Colonel De Bohun appeared in the open casement. Without a moment's delay he went up to his aunt, putting an arm tenderly round her. One glance at his pale face was sufficient.

'Godfrey, what is it?'

She was trembling, so that without support she could not have stood.

'Sit down, dear Aunt, and let me tell you,' he said, with more calmness than he felt.

He greatly dreaded the effect of his communication. Though she was always cheerful, active, and upright, he could not forget that she was old, and that any shock might be disastrous to her.

'Tell me,' she said, looking up into his face.

'We all imagined Estelle to be with you till her nurse came to fetch her. I was out when she came. The fact is, we had rather a fright about Alan. He had fallen down a hole in the rocks, and we were obliged to go to his rescue. He was got out with some difficulty, and on our way home we came across James, who told us of your anxiety about Estelle. Neither Marjorie nor Alan had seen her since they had left her reading to Georgie on the roof of the ruin. Marjorie, who had heard the door bang, found no one there when she reached the place, and the door was closed. Fearing something wrong, I sent James off at once for Peet, in order to see if the poor child had been accidentally locked into the forbidden room.'

'Yes?' whispered Lady Coke.

She looked so weak and shaken that the Colonel made her sit down in her armchair before he would go on with the story.
