“Well, you are not wearing it, so I presume you gave it back. Now, just let me hint to him, in the very most delicate way in the world, of course, that you miss that ring from your finger, and trust me, it will be back there before another hour is over, and you and he both as happy as——”

But, to Mrs Hardy’s astonishment and indignation, Mabel burst into a wild peal of laughter. “Oh, you mean that?” she cried. “Why, that happened centuries ago. I had forgotten all about it!”

CHAPTER XX.
THE FORCES OF NATURE.

The days dragged slowly by in the beleaguered fort. The enemy’s extraordinary dislike of coming to close quarters, and the consequent absence of direct attacks, tried the endurance of the garrison sorely. It showed, no doubt, that the tribes retained a wholesome remembrance of past hand-to-hand encounters, and were now actuated rather by a desire for loot than by any fanatical hatred of British rule; but it showed also that their leaders believed they had abundance of time before them. Moreover, while Bahram Khan maintained the investment with a cynical contempt for the relieving force which did not appear, the numbers of the defenders were dwindling. The death-roll did not indeed increase by leaps and bounds, as would have been the case after a series of fierce assaults, but the relentless monotony of its daily growth was scarcely less terrible. Disease had obtained a firm foothold in the crowded courtyards and narrow passages, and the supply of medicines and disinfectants was as limited as that of food had proved to be. A sowar dropped here, a Sikh there, next two or three of the wretched Hindu refugees, then one of the wounded in the hospital, unable to resist the poisoned atmosphere of the place. The tiny patch of garden—once the despair of the Club committee, because nothing but weeds would grow in it—which had been used as a cemetery, was soon over-full, and now silent burying-parties stole down nightly to the water-gate, and were ferried across the canal to conduct a hasty funeral on the opposite bank. Mabel and Flora will never forget the night they stood on the south rampart to see Captain Leyward’s body carried out. He had been desperately wounded when he took command of the escort in the Akrab Pass, after Dick was struck down, and although Dr Tighe was hopeful at first, it was not long before the case took an unfavourable turn. In order that the enemy should not discover these sallies of the garrison, the funeral rites were maimed indeed. There was no question of a band or a firing-party, and as it was not allowable even to use a lantern, Mr Hardy repeated portions of the Burial Service from memory. The grave, which had been hastily dug as soon as darkness came on, was made absolutely level with the surrounding sand as soon as it had been filled up. Its bearings were taken by compass in the hope of happier days to come, but no mark was placed upon it, for to point out that a British officer lay there would have been to invite the desecration of the spot. The two girls watched the dark mass of figures melt into the blackness beyond the embankment, and strained their eyes in vain to catch a glimpse of the group round the grave. They could see and hear nothing until the sudden creaking of the ferry-wires announced that the burial-party was returning, and soon afterwards Colonel Graham came up to the rampart and ordered them down to bed.

Mabel wondered very much what Georgia’s thoughts were at this time. She never alluded to the wild impulse which had led her to try and leave the fort, but she seemed to shrink into herself, and liked to be left alone with the baby for hours. When her friends came to speak to her, she showed an impatience that surprised them, until at last, in a burst of contrition for the irritation she had shown, she explained that she was listening for Dick’s voice. She could hear it sometimes when the baby and she were alone together, but if there were other people in the room, their voices seemed to drown it. “What did he say?” Mabel ventured to ask, awed by her sister-in-law’s tone of absolute conviction, and Georgia confessed, with some disappointment, that he had not said anything particular. It was as if they were just talking together as usual about things in general, and the conversation would break off abruptly, as if she was waking out of a dream. Mabel was disappointed also. If Dick could really speak to his wife from the dead, surely he would communicate his wishes about the boy’s bringing-up, or some subject of similar importance; but this casual talk—what could it be but a delusion of Georgia’s troubled brain, which could not distinguish between dreams and realities?

In the meantime, the reconnaissance which Fitz had made in company with Sultan Jān was not entirely destitute of results. The news that a mine was in course of construction had alarmed Colonel Graham more than he cared to show, although the most careful investigations possible in the circumstances went to prove that the tunnel had not at present reached the neighbourhood of the walls. Runcorn, who took the matter very much to heart, regarding it as a sign that he had not been sufficiently on the alert, obtained permission to make a solitary reconnaissance on two successive nights, and managed on the second occasion to creep across the cleared space, and up to the very walls of General Keeling’s house. By dint of long and careful listening, with his ear to the ground, he satisfied himself that work was going on briskly, but that the tunnel was not yet nearly long enough to threaten the east curtain. After this, he held much consultation with Fitz, and the two formulated a desperate scheme. They proposed to creep into the enemy’s entrenchments, carrying with them a supply of explosives, and blow up the mine before it was carried any farther, destroying at the same time General Keeling’s house, in the compound of which was the entrance shown to Fitz. The Colonel vetoed the plan promptly, but its inventors were not to be discouraged, and produced a fresh modification of it every day, until circumstances intervened with decisive effect to prevent its execution.

On a certain night Mabel awoke with the impression that she was passing anew through the most disagreeable experience of her voyage out—a gale in the Bay of Biscay. She could feel the ship trembling—it had been rolling just now—the passengers were screaming, and the wind seemed to be howling on all sides at once.

“A mast gone!” she said to herself, with a vague recollection of sea-stories read in youth, as she heard a fearful crash; “but the wind howls just as if we were on land. I wonder whether I had better try to get on deck? Why!—but how can we be on land?”

It was most confusing. She was awake now, and realised that the voyage had ended long ago, but it seemed impossible not to believe that she was still on board ship, for the floor was shaking when she stood upon it, and the little square of grey darkness which marked the position of the window was wavering about just as a porthole would naturally do in rough weather.

“Am I going mad?” Mabel demanded of herself, yielding to a sudden lurch, and sitting down unsteadily on the side of her bed. “No, I am actually beginning to feel sea-sick—that must be real, at any rate. Why, it must be the mine!”—she sprang up, and threw on her dressing-gown and a cloak over it—“and what about Georgie and the boy?”
