‘Mad!’ he thundered violently, slapping his knee and breaking into a short, semi-delirious laugh. He leaned forward as though he would take Miss Laura into his strictest confidence, and putting his hand to the side of his mouth he whispered, ‘She is mad. We none of us knew it, Laura. My first act, then, when we reach home will be to confine her. But not a word, mind!’ He held his finger to his lips and in that posture slowly leaned back in his chair again, with a face painful with its smile of cunning and triumph.

I saw that the girl was getting scared; so without ado I dropped out of the bunk on to my feet.

‘An excellent scheme, Wilfrid,’ said I; ‘in fact the only thing to be done. But, my dear fellow, d’ye know the atmosphere here is just roasting. I’ll take Miss Jennings on deck for a turn, and when I am cooled down a bit I’ll look in upon you for another yarn for half-an-hour before turning in.’

‘All right,’ he exclaimed. ‘Laura looks as if she wants some fresh air. Send one of the stewards to me, will you, as you pass through the cabin? But mind, both of you—hush! Not a word; you understand?’

‘Trust us,’ said I, and sick at heart I took Miss Laura’s hand and led her out of the cabin. As I closed the door she reeled and would have fallen but for the arm I passed round her. I conducted her to a couch and procured a glass of water. The atmosphere here was comparatively cool with the evening air breezing down through the wide skylight, and she quickly recovered.

‘It is terrible!’ she exclaimed, pressing her fingers to her eyes and shaking her head. ‘I should fall crazy myself were I much with him. His sneers, his smiles, his looks, the boyish air of his face too! The thought of his misery, his injury, the irreparable wrong done him—poor Wilf, poor Wilf!’ Her tender heart gave way and she wept piteously.

When she was somewhat composed she fetched a hat and accompanied me on deck. The dusk down to the horizon was clear and fine, richly spangled to where the hard black line of the ocean ruled the firmament. On high sailed many meteors, like flying-fish sparking out of the dark velvet; some of them scoring under the trembling constellations a silver wake that lingered long on the eye and resembled a length of moon-coloured steam slowly settling away before the breath of a soft air. There were many shooting stars, too, without the comet-like grace of the meteoric flights; sharp, bounding sparkles that made one think of the flashing of muskets levelled at the ocean by visionary hands in the hovering, star-laden gloom. The wind was failing; the yacht was sailing with erect masts with a rhythmic swinging of the hollows of her canvas to the light weather rolls of the vessel on the tender undulations. It was like the regular breathing of each great white breast. The dew was heavy and cooled the draught as a fountain the atmosphere round about it. A little sleepy noise of purring froth came from the bows. All was hushed along the decks, though as the yacht lifted forward I could make out some figures pacing the forecastle, apparently with naked feet, for no footfall reached the ear.

‘Alas,’ said I, ‘the wind is failing. I dread the stagnation of these waters. I have heard of ships lying becalmed here for two and three months at a stretch; in all those hideous days of frying suns and steaming nights scarce traversing twenty leagues.’

‘We were becalmed a fortnight on the Line,’ said Miss Laura, ‘on our passage to England. It seemed a year. Everybody grew quarrelsome, and I believe there was a mutiny amongst the crew.’
