The man knuckled his forehead and withdrew. The heat was so great owing to the companion hatch and skylight being closed, that my sweet companion seemed half-dead with it, and leaned against me with her eyes closed, almost in a swoon. But the worst of the storm was over apparently, for the rain had ceased, and though the lightning was still intensely vivid, one knew by the sound of the thunder that what was fiercest had forged ahead of us and was settling away into the north. I called to the steward to open the companion doors and report the state of the weather. The moment the hatch lay clear to the night I felt a gush of refreshing and rain-sweetened air. Laura sat upright and gave a deep sigh.

‘Does it rain, steward?’ I sung out.

‘No, sir.’

‘Tell Captain Finn,’ said I, ‘to get some space of deck swabbed dry for Miss Jennings. The heat here is too much for the young lady.’

In a few moments I heard the slapping of several swabs and Finn’s long face glimmered through the open skylight. ‘The weather’s a-clearing, sir,’ he called down. ‘There’s a nice little air a-blowing. The lady’ll find the port side of the quarter-deck comfortable now.’

I conducted the girl up the ladder, but she kept her hand in my arm. Her manner had something of clinging in it, not wholly due to fear either. It was, in fact, as though she was influenced by an overpowering sense of loneliness, easy to understand when one thought of Wilfrid lying mad in his cabin and her sister shunning her with hate and rage.

What Finn meant by saying the weather was clearing I could not quite understand. It was pitch black to windward, that is to say, right over the stern, whence there was a small breeze blowing in faint, fitful, weak gusts as though irresolute. The thunderstorm was ahead and its rage seemed spent, for the lightning was no longer plentiful or brilliant and the thunder had faded into a sullen muttering. A lantern or two had been brought up from below by whose feeble lustre you witnessed the shadowy forms of seamen swabbing the decks or squeezing the water with scrubbing-brushes into the scuppers. The dark swell ran regularly and with power from the south, but there was nothing to be seen of it saving here and there the glittering of green sea fire upon some running brow to let you guess how tall it was. I went aft with Laura and looked over; the wake was a mere dim, glistening, crawling, dying out after a few fathoms. Indeed, the yacht had but the foresail on her with a headsail or two, and she seemed to owe what small way she was making more to the heave of the swell than to the light breeze. The darkness was a wonderful jumble of shadows. I never remember the like of such confusion of inky dyes. The obscurity resembled an atmosphere of smoke denser in one place than another, a little thin yonder, then just over the mastheads a stooping belly of soot, elsewhere a sort of faintness merging into impenetrable darkness.

‘Lay aft and loose the mains’l,’ rattled out Finn. ‘Double reef and then set it.’

The breeze now began to freshen; the watch came running on to the quarter-deck, and presently the wan space of double-reefed canvas slowly mounted.
