By the time the week was out the enforced partial solitude, the constant chagrin, and the never-ending brooding which was thus engendered, began to make Mr. Markam quite ill. He was too proud to take any of his family into his confidence since they had in his view treated him very badly. Then he did not sleep well at night, and when he did sleep he had constantly bad dreams. Merely to assure himself that his pluck was not failing him he made it a practice to visit the quicksand at least once every day; he hardly ever failed to go there the last thing at night. It was perhaps this habit that wrought the quicksand with its terrible experience so perpetually into his dreams. More and more vivid these became, till on waking at times he could hardly realise that he had not been actually in the flesh to visit the fatal spot. He sometimes thought that he might have been walking in his sleep. One night his dream was so vivid that when he awoke he could not believe that it had only been a dream. He shut his eyes again and again, but each time the vision, if it was a vision, or the reality, if it was a reality, would rise before him. The moon was shining full and yellow over the quicksand as he approached it; he could see the expanse of light shaken and disturbed and full of black shadows as the liquid sand quivered and trembled and wrinkled and eddied as was its wont between its pauses of marble calm. As he drew close to it another figure came towards it from the opposite side with equal footsteps. He saw that it was his own figure, his very self, and in silent terror, compelled by what force he knew not, he advanced—charmed as the bird is by the snake, mesmerised or hypnotised—to meet this other self. As he felt the yielding sand closing over him he awoke in the agony of death, trembling with fear, and, strange to say, with the silly man’s prophecy seeming to sound in his ears: “‘Vanity of vanities! All is vanity!’ See thyself and repent ere the quicksand swallow thee!” So convinced was he that this was no dream that he arose, early as it was, and dressing himself without disturbing his wife took his way to the shore. His heart fell when he came across a series of footsteps on the sands, which he at once recognised as his own. There was the same wide heel, the same square toe; he had no doubt now that he had actually been there, and half horrified, and half in a state of dreamy stupor, he followed the footsteps, and found them lost in the edge of the yielding quicksand. This gave him a terrible shock, for there were no return steps marked on the sand, and he felt that there was some dread mystery which he could not penetrate, and the penetration of which would, he feared, undo him.
