The House of Defence, Volume II by E.F. Benson

Thurso's recovery, though he had had no relapse of any kind, and no hint of a second attack, had been slow, and it was more than three weeks from the time of his collapse when he and Maud were sitting together on the deck of the _Celtic_, Westward-bound, watching the shores of Ireland fade into blurred outlines of grey, as they were fused with the horizon. They had embarked the day before at Liverpool, and though they had been at sea only twenty-four hours, there was already some semblance of colour beginning to come back to his face. But if Maud had met him now after a year's absence, she felt that she would scarcely have known who he was. Those months of indulgence in the drug had altered the whole character of his face: it was not of the same man. It had made him look strangely wan and old, too. The heavy dint of crows' feet was planted on the outer corners of his eyes, and the lids were slack, baggy, and pendulous.

His eyes had changed; they looked stale and dead, but it was his mouth, perhaps, that had deteriorated most: all power and force were gone from it; it drooped feebly and weakly at its corners, and the lower lip hung flabby and loose. It was the mouth of a man ruined by self-indulgence. His hair, too, had become very thin, and streaks of grey had appeared in it. And all this was but the shadow of the real wreck within.
