“Very well, Arthur! Of course you will do as you choose. Make me as ridiculous as you can, and spoil the poor girls’ chances in life. Young men don’t seem to care, as a general rule, for an idiot father-in-law! But I must warn you that your vanity will some day get a rude shock—if indeed you are not before then in an asylum or dead!”

It was manifest after a few days that Mr. Markam would have to take the major part of his outdoor exercise by himself. The girls now and again took a walk with him, chiefly in the early morning or late at night, or on a wet day when there would be no one about; they professed to be willing to go out at all times, but somehow something always seemed to occur to prevent it. The boys could never be found at all on such occasions, and as to Mrs. Markam she sternly refused to go out with him on any consideration so long as he should continue to make a fool of himself. On the Sunday he dressed himself in his habitual broadcloth, for he rightly felt that church was not a place for angry feelings; but on Monday morning he resumed his Highland garb. By this time he would have given a good deal if he had never thought of the dress, but his British obstinacy was strong, and he would not give in. Saft Tammie called at his house every morning, and, not being able to see him nor to have any message taken to him, used to call back in the afternoon when the letter-bag had been delivered and watched for his going out. On such occasions he never failed to warn him against his vanity in the same words which he had used at the first. Before many days were over Mr. Markam had come to look upon him as little short of a scourge.

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.

In this state of affairs he took two wrong courses. Firstly he kept his trouble to himself, and, as none of his family had any clue to it, every innocent word or expression which they used supplied fuel to the consuming fire of his imagination. Secondly he began to read books professing to bear upon the mysteries of dreaming and of mental phenomena generally, with the result that every wild imagination of every crank or half-crazy philosopher became a living germ of unrest in the fertilising soil of his disordered brain. Thus negatively and positively all things began to work to a common end. Not the least of his disturbing causes was Saft Tammie, who had now become at certain times of the day a fixture at his gate. After a while, being interested in the previous state of this individual, he made inquiries regarding his past with the following result.

Saft Tammie was popularly believed to be the son of a laird in one of the counties round the Firth of Forth. He had been partially educated for the ministry, but for some cause which no one ever knew threw up his prospects suddenly, and, going to Peterhead in its days of whaling prosperity, had there taken service on a whaler. Here off and on he had remained for some years, getting gradually more and more silent in his habits, till finally his shipmates protested against so taciturn a mate, and he had found service amongst the fishing smacks of the northern fleet. He had worked for many years at the fishing with always the reputation of being “a wee bit daft,” till at length he had gradually settled down at Crooken, where the laird, doubtless knowing something of his family history, had given him a job which practically made him a pensioner. The minister who gave the information finished thus:—

“It is a very strange thing, but the man seems to have some odd kind of gift. Whether it be that ‘second sight’ which we Scotch people are so prone to believe in, or some other occult form of knowledge, I know not, but nothing of a disastrous tendency ever occurs in this place but the men with whom he lives are able to quote after the event some saying of his which certainly appears to have foretold it. He gets uneasy or excited—wakes up, in fact—when death is in the air!”

This did not in any way tend to lessen Mr. Markam’s concern, but on the contrary seemed to impress the prophecy more deeply on his mind. Of all the books which he had read on his new subject of study none interested him so much as a German one Die Döppleganger, by Dr. Heinrich von Aschenberg, formerly of Bonn. Here he learned for the first time of cases where men had led a double existence—each nature being quite apart from the other—the body being always a reality with one spirit, and a simulacrum with the other. Needless to say that Mr. Markam realised this theory as exactly suiting his own case. The glimpse which he had of his own back the night of his escape from the quicksand—his own footmarks disappearing into the quicksand with no return steps visible—the prophecy of Saft Tammie about his meeting himself and perishing in the quicksand—all lent aid to the conviction that he was in his own person an instance of the döppleganger. Being then conscious of a double life he took steps to prove its existence to his own satisfaction. To this end on one night before going to bed he wrote his name in chalk on the soles of his shoes. That night he dreamed of the quicksand, and of his visiting it—dreamed so vividly that on walking in the grey of the dawn he could not believe that he had not been there. Arising, without disturbing his wife, he sought his shoes.

The chalk signatures were undisturbed! He dressed himself and stole out softly. This time the tide was in, so he crossed the dunes and struck the shore on the further side of the quicksand. There, oh, horror of horrors! he saw his own footprints dying into the abyss!
