The under-Secretary by William le Queux

To love faithfully is to love with singleness of heart and sameness of purpose, through all the temptations which society presents, and under all the assaults of vanity both from within and without. It is so pleasant for a woman to be admired and so soothing to her to be loved, that the grand trial of female constancy is to refrain from adding one more conquest to her triumphs when it is evidently in her power to do so. Obviously her chief protection is to restrain the first indefinite thoughts which, if allowed to gain clearness and swiftness, may lead her fancy astray. Even the ideas which commonly float through the mind of woman are so rapid and so indistinctly shaped, that when the door is opened to such thoughts as these they pour in like a torrent.

Then first will arise a sudden perception of deficiency in the object of her love, or some additional impression of his unkindness or neglect, with comparisons between him and other men, and regret that he has not some quality which they possess; sadness under a conviction of her future destiny, pining for sympathy under that sadness, and, lastly, the commencement of some other intimacy, which at first she has no idea of converting into love.
