"√ã bientôt," she cried.

"Au revoir, Madame." He saw her hurried into the launch, which immediately got under way, its exhaust snorting furiously, and vanished around the point of rocks. In a moment there was nothing left of his visitors to Markham but the lapping of the waves from the launch upon the beach and the spot in the air which was not almost imperceptible.

He stood there until he could see it no more, when he turned and took his pipe thoughtfully from his trousers pocket and addressed it with conviction.

"Mad!" he muttered. "All—quite mad!"

CHAPTER VII

"WAKE ROBIN"

Markham climbed the hill slowly, pushing tobacco into his pipe. Once or twice he stopped and turned, looking out over the bay toward the distant launch. The aëroplane had vanished. When he reached the bungalow he dropped into a chair, his gaze on space, and smoked silently for many minutes.

Mad! Were they? Madness after all was merely a matter of relative mental attitudes. Doubtless he was as mad in the eyes of his visitors as they were to him. In his present mood he was almost ready to admit that the sanest philosophy of life was that which brought the greatest happiness. And sanity such as his own was only a sober kind of madness after all, a quiet mania which sought out the soul of things and in the seeking fed itself upon the problems of the world, a diet which too much prolonged might lead to mental indigestion. Morbid—was he? Introspective? A "grouch"? He was—he must be—all of these things.

His small inquisitor had neglected none of his failings, had practiced her glib tongue at his expense in the few hours in which she had taken possession of Thimble Island and of him. What a child she was, how spoiled and how utterly irresponsible! He identified her completely now, Hermia Challoner, the sole heiress of all Peter Challoner's hard-gotten millions, the heiress, too, it was evident, of his attitude toward the world, the flesh and the devil; Peter Challoner, by profession banker and captain of industry, a man whose name was remembered the breadth of the land for his masterly manipulation of a continental railroad which eventually came under his control; an organizer of trusts, a patron saint of political lobbyists, a product of the worst and of the best of modern business! This girl who had fallen like a bright meteor across Markham's sober sky this morning was Peter Challoner's daughter. He remembered now the stories he had heard and read of her caprices, the races on the beach at Ormonde, her fearlessness in the hunting field and the woman's polo team she had organized at Cedarcroft which she had led against a team of men on a Southern field. It had all been in the newspapers and he had read of her with a growing distaste for the type of woman which American society made possible. Peter Challoner's daughter, the spoiled darling of money idolaters, scrubbing the floor of his kitchen!

As he sat looking out over the bay thinking of his visitor, a picture rose and wreathed itself amid the smoke of his tobacco—the vision of a little working girl in New York, a girl with tired eyes and a patient smile, with the faded hair and the faded skin which came from too few hours of recreation—from too many uninterrupted hours of plodding grind at the tasks her employers set for her, a girl who would have been as pretty as Hermia Challoner if her youth had only been given its chance. This was Dorothy Herick, whose father, a friend of Markham's father, had been swallowed up in one of the great industrial combinations which Peter Challoner had planned. Markham, who had been studying in Paris at the time, had forgotten the details of Oliver Herrick's downfall, but he remembered that the transaction which had brought it about had not even been broadly in accordance with the ethics of modern business, and that there had been something in the nature of sharp practice on Peter Challoner's part which had enabled him to obtain for his combination the mills in the Wyoming Valley which had been in the Herrick family for three generations.
