These experiences continued at varying intervals; and presently Joan began to understand that Quard had not only primarily a weakness to tempt him, but a constitutional inability to assert his will-power after he had surrendered to the extent of a single drink. One modest dose of alcohol seemed to exercise upon him a sort of hypnotic power, driving him on whether he would or not to the next, the next, and the next--until the nadir of unconsciousness was reached. It was not that he invariably succumbed to moderate indulgence, but that once started he rarely stopped until his identity was completely submerged. Indeed, the way of alcohol with him seemed never twice to follow the same route; but its end was invariably the same. Hoping against hope, fighting with him, pleading, reasoning, threatening with him, even praying, Joan endured for a long time--much longer than, in retrospective days, seemed possible even to her; for she was honestly fond of her husband, far more so than she was ever of any other living being save herself. They reached San Francisco the third week in April. For some time Quard had been drinking rather methodically but stealthily. A threat made by Joan, while he was sobering up from his last debauch, to the effect that on repetition of the offence she would leave him without an hour's notice, had frightened the man to the extent of making him hesitate to add one drink to another except at intervals long enough to retard the cumulative effect; but never a day passed on which, in spite of her watchfulness, he did not contrive to throw several sops to the devil in possession, if without ever quite losing his wits. Detected with reeking breath, he would adopt one of three attitudes: he was a man, subject to the domination of no woman and of no appetite, had learned his lesson and now knew when to stop; or he was sorry--hadn't stopped to think--and wouldn't let it go any further; or nothing of the sort had happened, he had drunk nothing except a glass of soda-fountain nerve-tonic, or possibly it was his cigar that she smelled. With the first, Joan had no patience; and since she had a temper, it was the last resort in Quard's more sober stages, seldom employed save when potations had made him either indifferent or vicious. In his contrition, whether real or assumed, she tried hard to believe. But his lies never deceived her: to these she listened in the silence of contempt and despair. On the Wednesday afternoon of their week in San Francisco, the girl did a bit of shopping after the matinée; it was half after five before she returned to the hotel, and walked into their room to find Quard, with his coat off, seated in a chair that faced the door. His back was to the windows, through which the declining sun threw a flood of blinding golden light, so that Joan's dazzled vision comprehended only the dark silhouette of his body.
