A Son of Perdition by Fergus Hume

For six months after the death of her father Alice travelled abroad, with Mrs. Sparrow as her chaperon and companion. The strain to which she had been subjected demanded removal from surroundings so intimately connected with the ordeal, and meanwhile Tremore could be safely left in charge of the housekeeper. It was with some reluctance that Montrose agreed to the Continental tour, which had been suggested by Eberstein, as it parted him for half a year from the girl he loved. But the doctor pointed out that absence would make Alice more self-reliant, since she would have to deal single-handed with her sorrow, unaided by her lover's sympathy and companionship. Each human being, he declared, must learn to become a centre of power, depending on God alone for help, since only in this way can such a one develop the necessary strength to act as a useful servant of Christ.

It was a drastic training for the young people, at which they winced; but when Eberstein fully convinced them that the flesh must be dominated by the spirit at all costs, they agreed to the separation. It was a final test of their obedience, and a great one.
