Whether or not this pair were man and wife, I had seen abundant reason to doubt the friendliness of their relation. Although Icould 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 manoeuvres, 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.
The day was so agreeable, being calm and sunshiny, with a tranquil sea, and yet with a healthful piquancy and vigour in the air, that, contrary to custom, she was tempted forth a second time to walk.
On this occasion she was accompanied by Northmour, and they had been but a short while on the beach, when I saw him take forcible possession of her hand. She struggled, and uttered a cry that was almost a scream. I sprang to my feet, unmindful of my strange position; but, ere I had taken a step, I saw Northmour bareheaded and bowing very low, as if to apologise; and dropped again at once into my ambush. A few words were interchanged; and then, with another bow, he left the beach to return to the pavilion. He passed not far from me, and I could see him, flushed and lowering, and cutting savagely with his cane among the grass. It was not without satisfaction that I recognised my own handiwork in a great cut under his right eye, and a considerable discolouration round the socket.
For some time the girl remained where he had left her, looking out past the islet and over the bright sea. Then with a start, as one who throws off preoccupation and puts energy again upon its mettle, she broke into a rapid and decisive walk. She also was much incensed by what had passed. She had forgotten where she was. And I beheld her walk straight into the borders of the quicksand where it is most abrupt and dangerous. Two or three steps farther and her life would have been in serious jeopardy, when I slid down the face of the sand-hill, which is there precipitous, and, running half-way forward, called to her to stop.
She did so, and turned round. There was not a tremor of fear in her behaviour, and she marched directly up to me like a queen. Iwas barefoot, and clad like a common sailor, save for an Egyptian scarf round my waist; and she probably took me at first for some one from the fisher village, straying after bait. As for her, when I thus saw her face to face, her eyes set steadily and imperiously upon mine, I was filled with admiration and astonishment, and thought her even more beautiful than I had looked to find her. Nor could I think enough of one who, acting with so much boldness, yet preserved a maidenly air that was both quaint and engaging; for my wife kept an old-fashioned precision of manner through all her admirable life - an excellent thing in woman, since it sets another value on her sweet familiarities.
"What does this mean?" she asked.
"You were walking," I told her, "directly into Graden Floe.""You do not belong to these parts," she said again. "You speak like an educated man.""I believe I have right to that name," said I, "although in this disguise."But her woman's eye had already detected the sash. "Oh!" she said;"your sash betrays you."
"You have said the word BETRAY," I resumed. "May I ask you not to betray me? I was obliged to disclose myself in your interest; but if Northmour learned my presence it might be worse than disagreeable for me.""Do you know," she asked, "to whom you are speaking?""Not to Mr. Northmour's wife?" I asked, by way of answer.
She shook her head. All this while she was studying my face with an embarrassing intentness. Then she broke out -"You have an honest face. Be honest like your face, sir, and tell me what you want and what you are afraid of. Do you think I could hurt you? I believe you have far more power to injure me! And yet you do not look unkind. What do you mean - you, a gentleman - by skulking like a spy about this desolate place? Tell me," she said, "who is it you hate?""I hate no one," I answered; "and I fear no one face to face. My name is Cassilis - Frank Cassilis. I lead the life of a vagabond for my own good pleasure. I am one of Northmour's oldest friends;and three nights ago, when I addressed him on these links, he stabbed me in the shoulder with a knife.""It was you!" she said.
