They had exchanged rings and locks of hair in the most orthodox fashion. It was arranged that Rookleigh should be the medium through which their correspondence should be conducted, their letters being mutually, if necessary, sent under cover to him. There could be no harm in their hearing of each other secretly, they thought, and deemed such an institution necessary for their happiness—their very existence, indeed; for both were rash, young, loving, and enthusiastic, and both, too, were somewhat ignorant of the conventional ways of the world; and to Rookleigh now they both mutually looked for succour in the great love that bound their hearts together.

Though his heart was weary with the keen sorrow of their separation, Derval felt full of bright hope for the future—that hope which furnishes all our Chateaux in Espagne, or in the air—"hope that lends us alabaster bricks and golden mortar to build these castles withal; hope that turns the hue of the stalest loaf into the richest plum-cake, and the smallest of beer into the mellowest of Burgundy."

As if chance were already beginning to favour him, Derval, who did not, and never would visit the villa at Finglecombe, on returning to the hotel found his brother Rookleigh awaiting him there.

"You asked me the other day if I would do you a favour, Rook," said he, "and I promised to do it—though I was in a great hurry."

"Yes—Miss Hampton was waiting for you on the beach. I saw you meet—well?"

"You must in turn do a favour for me—and I am sure you will, old fellow!" added Derval, and he placed a hand affectionately on his brother's shoulder, feeling at that moment, in the great joy of being loved by Clara, that he forgave him everything, and could love him too.

He then related to Rookleigh much that had passed between himself and Clara—told of their secret engagement—secret, at least, as yet; showed her engagement-ring, but failed to see the sneer of Rookleigh's lip, as he kissed it with what the latter deemed idiotic ardour; and in the end, begged him to be the medium through whom their correspondence was to be conducted; and to this Rookleigh, affecting demurrage, ultimately consented, for which he was extravagantly thanked and well-nigh embraced by Derval, who said:

"And now, Rook, dear old boy, what is the favour you wanted of me—in what can I serve you?"

An unfathomable expression stole over the face of Rookleigh at that moment, and his pale green shifty hazel eyes perhaps never looked so shifty. Skilfully veiled hatred, malice, and anticipated triumph were mingling there; but Derval, whose heart and thoughts were utterly strangers to passions such as these, could little have conceived they were so near him.

We have said that both Mrs. Hampton and Rookleigh resented Derval's intimacy with Lord Oakhampton, and the revengeful feeling of the half-brother eventually took a very remarkable form.
