Passing into the deck corridor, she heard the captain’s voice, apparently at a considerable distance. Two hundred yards away from the ship, Courtenay and Tollemache were anchoring a flat framework, built of spare hatches and secured by wooden cross-pieces. On it stood the first of the infernal machines. The raft floated level with the water, so its only conspicuous fitting was a small spar and a block, to which a line and an iron bar were attached. The men looked strange in her eyes at that distance. In the marvellously clear light she could see their features distinctly, and, when Courtenay shouted to a sailor to haul in the slack of the line, she caught a trumpet-like ring that recalled the scene in the saloon when he held back the mob of stewards. His athletic figure, silhouetted against the shimmering green of the water, was instinct with graceful strength. He looked a born leader of men, and, as though to mark his quickness of observation, no sooner had Elsie glanced over the side of the ship than he waved a hand to her.

She sighed. A bitter thought peeped up in her that he was perhaps a trifle careless in showing her these little attentions. She wished he would speak to her of that other girl who awaited him in England. A pleasant state of confidence would be established then; these secret twitches of sentiment were irritating.

Some women, in her place, would pay no heed to that aspect of their enforced relations; not so Elsie, whose virginal breast was unduly fluttered by the discovery that a young man is the most natural thing in the world for a young woman to think about.

She walked aft to obtain a nearer view of the operations. The sailors had already shut in a large portion of the promenade deck with canvas, and she noticed that loopholes were provided, every ten feet or so, to permit the effective use of the defenders’ firearms. Thus, at each step, she was reminded of the precarious hold she had on life, and she was positively frightened when some mad impulse surged through her whole being, bidding her imperiously to abandon her ultra-conscientious loyalty to a woman she had never seen. Why struggle against circumstance? If death were so near, what did she gain by prudery?

For an instant she stood aghast at the revelation which had come to her. She was in love with Courtenay. She was ready to die by his side, fearless and joyous, if only he would put his arms around her and tell her that she was dear to him. Ah, the fierce delight of that first silent surrender! Her heart beat as it had never pulsed before, even under the stress of the storm or the sudden terror of the night attack. Her eyes shone, and her breath came laboriously between parted lips. Golden dreams coursed through her brain. She was thrilled with an unutterable longing.

Then her swimming eyes rested on a group of men standing on the poop. Among them was Christobal, interested, like the rest, in the floating of the mine. And forthwith Elsie fell from the clouds, and was brought back, shuddering, to cold reason again. She was sick at heart; she hated herself for her self-abasement. She must gird her with sackcloth and mourn; and the fight must be fought now, without parley or hesitation, unless the sweetness were to go forth from life for ever, and all things should turn to ashes in her mouth.

So, marshaling the best qualities of her womanhood, she quelled the turmoil in her breast, forced herself to join the men on the after deck, and said, when the smiling Spaniard turned to receive her:

“Why am I denied the mild excitement of mine-laying, Dr. Christobal? Is it that you dread the effect on my nerves of these murderous preparations?”

“No,” he answered, making room for her at the railing by his side. “I had missed you, of course, but I thought you were resting.”

“Resting, indeed! I have been quite busy. Where do they mean to put the second contrivance?”
