And then the two figures sped onward, side by side. They were watched with keen speculative interest by the occupants of the boats. No one, save simple Mrs. Verschoyle, felt disturbed as to the Doctor’s ultimate fate. Was an old gentleman who had taken admirable care of himself for forty years in India a likely subject to be spirited away on the sands, between Luc and Langrune? But the situation had a dramatic piquancy that stirred even the unimaginative minds of the Miss de Carterets and their attendant subalterns. For there was Dinah! Impossible to forget that Mrs. Gaston Arbuthnot, that lowly-born young woman with the beautiful eyes, and set, sad mouth, was also watching the two figures as they disappeared in the darkness.

‘A quarter of an hour. By Jove! ten minutes of that quarter must be nearly gone.’

And taking out his watch, Lord Rex struck a vesuvian in order to learn the time. It was exactly eight minutes to nine, and at nine, sharp, the Princess was to weigh her anchor. The moment for action had come. Now, what was the wisest thing to do? One point seemed certain—it was useless for both boats to wait longer. Let the smaller boat, at the head of the jetty, start for the steamer at once, let the captain be told what had happened, and asked to put off his departure as long as practicable. If Gaston Arbuthnot and the Thornes arrived in time, the second boat would bring them off. If not—why, common sense could really dictate no better plan than Gaston’s own. Langrune was not the end of the world A railway to Cherbourg existed. The Lady of the Isles would no doubt bring the lost sheep comfortably back to their respective folds to-morrow.

Dinah as it happened was, with Ada de Carteret and the elder ladies, in the boat at the head of the jetty. And soon before Dinah’s eyes, as before the eyes of one who dreams, the reflections of the Casino lamps, the children’s Chinese lanterns, were dancing with fairy-like brightness across the moving water. She realised that her day of pleasure was over, that every one—yes, she could catch the voices of Marjorie and of Geff, holding merry talk in the other boat—every one took the adventure jestingly, and that her heart felt like lead, that her hands were ice-cold, that each breath she drew was a conscious and painful effort. Well—if she had enough bodily strength to act her part out, she thought, say no word to betray her plebeian emotions, and so bring down ridicule on her husband or herself, she must be content! Once on board the steamer she could hide herself in the cabin, away from sight, and there wait, until the comedy (or tragedy) had reached its next act. This one wretched comfort remained to her. She would be able to screen herself, for a while at least, from observation—to be alone!

But a new and still more diverting incident was about to be woven into the text of the play.

‘If I were not in such a nervous state,’ cried Mrs. Verschoyle, when the boat was within three or four lengths of the Princess, ‘if I were not so morally shaken that I distrust my own senses, I should say our good Doctor was on board. There came a flash of light just now beside the wheel, the lighting, perhaps, of a fusee, and for a second it seemed to me that I saw Doctor Thorne’s figure distinctly. A pity some reliable person was not looking!’

And Mrs. Verschoyle, to her own surprise, had seen correctly. The Doctor it proved to be—the Doctor smoking one of the ship’s best cheroots, and enjoying the summer night with unruffled innocence. He advanced gallantly to assist the ladies in their embarkation, and heard with gusto the story of his own supposed fate. Surrounded by the tide? Tut, tut! Linda might have known, had she exercised her reason, whither he had betaken himself. ‘Only you ladies never do reason,’ said the Doctor, addressing Mrs. Verschoyle. ‘It was growing damp on shore—and let me give you a bit of advice, my dear madam: whenever you feel that clinging kind of chill, after gun-fire, get on board ship, if you have the chance. Get an honest plank, instead of the abominable miasmal emanations of Mother Earth, under your feet. Yes, yes,’ went on the Doctor comfortably, ‘I hailed one of the Princess’s boats and came on board two hours ago, have drunk my cup of coffee, and beaten Ozanne at his own game, cribbage.’

‘And your wife’s anxiety?’

‘My dear Mrs. Verschoyle, I am penitent! Only my wife, you see, might have reasoned. It would have deprived you all, no doubt, of a harmless excitement; but Linda, I think, might have reasoned. Any way, it is better to be drowned by one’s friends’ imaginations than run the risk, in earnest, of a pair of damp shoes.’
