The tall man seemed to have disappeared. Not only did he never cross the threshold, but he never so much as showed face at a window; or, at least, not so far as I could see; for I dared not creep forward beyond a certain distance in the day, since the upper floors commanded the bottoms of the links; and at night, when I could venture further, the lower windows were barricaded as if to stand a siege. Sometimes I thought the tall man must be confined to bed, for I remembered the feebleness of his gait; and sometimes I thought he must have gone clear away, and that Northmour and the young lady remained alone together in the pavilion. The idea, even then, displeased me. Whether or not this pair were man and wife, I had seen abundant reason to doubt the friendliness of their relation. Although I could hear nothing of what they said, and rarely so much as glean a decided expression on the face of either, there was a distance, almost a stiffness, in their bearing which showed them to be either unfamiliar or at enmity. The girl walked faster when she was with Northmour than when she was alone; and I conceived that any inclination between a man and a woman would rather delay than accelerate the step. Moreover, she kept a good yard free of him, and trailed her umbrella, as if it were a barrier, on the side between them. Northmour kept sidling closer; and, as the girl retired from his advance, their course lay at a sort of diagonal across the beach, and would have landed them in the surf had it been long enough continued. But, when this was imminent, the girl would unostentatiously change sides and put Northmour between her and the sea. I watched these maneuvers, for my part, with high enjoyment and approval, and chuckled to myself at every move. On the morning of the third day, she walked alone for some time, and I perceived, to my great concern, that she was more than once in tears. You will see that my heart was already interested more than I supposed. She had a firm yet airy motion of the body, and carried her head with unimaginable grace; every step was a thing to look at, and she seemed in my eyes to breathe sweetness and distinction.
