“Are all landscape gardeners atheists?” she asked, naïvely.

“I’m sure I don’t know,” Grey replied, smiling; “I’ve never investigated their religious beliefs.”

“Well, the one who designed all this,” she added, with a sweep of her hand, “had very little respect for God’s taste.”

And later, as they sauntered through room after room and gallery after gallery of the palace, with their interminable succession of paintings and sculptures, she was much impressed by the pictured ceilings.

“I wonder why they put their best work where one must break one’s neck to see it?” she queried; and then she laughed. “Do you suppose it was to encourage the kings and queens and other grandees to bear in mind their exalted position and to hold their heads high?”

Grey had thus far refrained from broaching the subject which had inspired the excursion. He had chosen first of all to study the girl and gauge her character. Over her presence in the little party of questionables in which he had so unexpectedly found himself he was much perplexed. It seemed scarcely reasonable to suppose that she was not in some way involved in the plot, but whether actively or passively, with knowledge or without, was, or at least might be, open to question. He certainly could gather no indication from her attitude, her manner, or her utterance that she was other than artless and sincere. She appeared, in fact, uncommonly simple-hearted, straightforward, and guileless, and, after weighing the evidence, he reached the conclusion that if she had a place in the scheme of his enemies it was most assuredly without her ken or connivance. It was nevertheless clear that she must be innocently aware of much that he wished eagerly to know, and, as they wandered over the palace together, from the sumptuously decorated Salles des Croisades, reflecting in picture, trophy and souvenir the conquest of Jerusalem and the Holy Sepulchre, to the magnificent Galerie des Glaces, with its many high-arched windows and glittering, gilt-niched mirrors, he ponderingly strove to outline some course of procedure that would yield him what he desired and yet not reveal his own delicately fragile position.

It was not, however, until they had finished their inspection of the palace and had passed out into the gardens by the Cour des Princes that an opportunity offered to make trial of the plan he had conceived. They had strolled under the orange trees beside that long stretch of velvet lawn towards what is known as the basin of Apollo and had found seats on the marble coping of the fountain. As they sat there facing each other amid the perfume of the flowers and the spice of the shrubbery, the balmy breath of summer fanning their cheeks and the genial glow of a tempered June sun bathing them, the girl’s eye fell for the first time upon the ring on Grey’s little finger, and she gave an involuntary start of surprise.

“Oh, is it you, then?” she cried, and there was something of awe in her voice, though her eyes were smiling. “But no,” she added, quickly, “that cannot be. I do not understand, Uncle Max.”

“Nor I, child,” Grey replied, smiling back at her. He had not observed her glance, and her exclamation had startled him. She took his hand in her long, white, rose-tipped fingers and held it up before his eyes, the ring glinting in the sunshine.

“That!” she said. “What does it mean, your wearing it?”
