Love Eternal by H. Rider Haggard

As it chanced Godfrey did see Isobel once more before he left England. It was arranged that he was to leave Charing Cross for Switzerland early on a certain Wednesday morning. Late on the Tuesday afternoon, Mr. Knight brought the lad to the Charing Cross Hotel. There, having taken his ticket and made all other necessary arrangements, he left him, returning himself to Essex by the evening train. Their farewell was somewhat disconcerting, at any rate to the mind of the youth.

His father retired with him to his room at the top of the hotel, and there administered a carefully prepared lecture which touched upon every point of the earnest Christian's duty, ending up with admonitions on the dangers of the world, the flesh, and the devil, and a strong caution against frivolous, unbelieving and evil-disposed persons, especially such as were young, good-looking and wore petticoats.
