"Yes," said Peter, encouragingly, as she hesitated. "You were about to say, a time when----?" Her lips moved, a faint flush stole into her cheeks; she was about to complete her sentence, when her hand seemed to melt away in his own, and he stood, grasping the empty air, by his own mantelpiece. The upper deck, the heaving bows, the blue seaboard, Miss Tyrrell herself, all had vanished; and in their stead were the familiar surroundings of his chamber, the grimy London house fronts, and Sophia's list of questions lying still unanswered upon his writing-table! His fifteen minutes had come to an end; the cheque was nowhere to be seen. The minute-hand of his clock had not moved since he last saw it; but this last circumstance, as he saw on reflection, was only natural, for otherwise the Time Deposit would have conferred no real advantage, as he would never have regained the hours he had temporarily foregone. For some time Peter sat perfectly still, with his head between his hands, occupied in a mental review of this his initial experience of the cheque-book system. It was as different as possible from the spell of perfect rest he had anticipated; but had it been unpleasant on that account? In spite of an element of mystification at starting, which was inevitable, he was obliged to admit to himself that he had enjoyed this little adventure more than perhaps he should have done. With all his attachment to Sophia, he could hardly be insensible to the privilege of suddenly finding himself the friend--and more than that, the dear friend--of so delightful a girl as this Miss Tyrrell. There was a strange charm, a peculiar and quite platonic tenderness about an intimacy of this peculiar and unprecedented nature, which increased at every fresh recollection of it. It increased so rapidly indeed, that almost unconsciously he drew the cheque-book towards him, and began to fill up another cheque with a view to an immediate return to the _Boomerang_. But when he had torn the cheque out, he hesitated. It was all quite harmless: the most severe moralist could not convict him of even the most shadowy infidelity towards his _fiançée_, if he chose to go back and follow up a purely retrospective episode like this--an episode which interested and fascinated him so strongly--only, what would Sophia say to it? Instinctively, he felt that the situation, innocent as it was, would fail to commend itself to her. He had no intention of informing her, it was true; but he knew that he was a poor dissembler--he might easily betray himself in some unguarded moment, and then---- No! it was vexing, no doubt; but, upon the whole, it was wiser and better to renounce those additional hours on board the _Boomerang_ altogether--to allow this past, that never had, but only might have been, to remain unsummoned and unknown for ever. Otherwise, who could tell that, by gradual assaults, even such an affection as he had for Sophia might not be eventually undermined?
