PROLOGUE. For months past, she had felt that she was weakening, that the crescent wretchedness of five long years—an uninterrupted descent from level to level, on each of which the thorns of disillusion caught at, and tore from her, some shred of hope or self-respect—had done its work at last. Her courage and her faith, inherited, the one from the mental, the other from the moral, vigour of a rigid and uncompromising Puritan ancestry, were slipping from her. What the end was to be, she did not dare to ask; but it lay there ahead, grim and ominous, gradually taking form, through the mist of the immediate future. Its very suggestion of divergence from all that was familiar to her, of being even a degree more monstrous than what she had already suffered, sickened and appalled her, who had never known a dread of mere death, but drew back with unspeakable fear before the looming of this unknown, ultimate degradation.

They were made for each other, people said, and no one subscribed more confidently to this opinion than themselves. But—and does ever a honeymoon pass without the uneasy awakening of that latent 'But'?—Helen was not a month older before she was forced to the unwilling conclusion that there was a singular, intangible something lacking in her husband's character.
