In London there once lived an old man named Harmon who had made a great fortune by gathering the dust and ashes of the city and sorting it for whatever it contained of value. He lived in a house surrounded by great mounds of dust that he had collected.

He was a hard-hearted man and when his daughter would not marry as he wished he turned her out of the house on a winter\'s night. The poor girl died soon after, and her younger brother (a boy of only fourteen), indignant at his father\'s cruelty, ran away to a foreign country, where for years he was not heard of.

The old man, hard-hearted as he was, and though he never spoke of the son save with anger and curses, felt this keenly, for in his own way he had loved the boy.

A Mr. Boffin was foreman of Harmon\'s dust business, and both he and his wife had loved the two children. Being kind and just people, they did not hesitate to let the father know how wicked they considered his action, and they never ceased[Pg 326] to grieve for the poor little John who had run away. So, though they did not guess it, the old man made up his mind they were an honest and deserving pair.

One morning the dust collector was discovered dead in his bed, and then it was found that he had left a very curious will. The will bequeathed all his vast fortune to the son who had run away, on one condition: that he marry a young lady by the name of Bella Wilfer, the daughter of a poor London clerk.

The son had never seen Bella in his life, and in fact the old man himself had seen her only a few times—and that was a long, long time before, when she was a very little girl. He was sitting in the park one Sunday morning, and the baby Bella, because her father would not go the exact way she wanted, was screaming and stamping her little foot. Old Mr. Harmon, having such a stubborn temper himself, admired it in the little child, and came to watch for her. Then, for some strange reason, which nobody ever could guess, he had put the baby\'s name in his will, declaring that his son John should get his money only by marrying this little girl. And the will declared, moreover, that if the son, John Harmon, should die, or should refuse to marry Bella, all the fortune should go to Mr. Boffin.

The lawyers had great trouble in finding where John Harmon was, but finally they did so, and received[Pg 327] word that he would return at once to England.

The ship he sailed on reached London, but the passenger it carried did not appear. A few days later, a riverman named Hexam found a body floating in the River Thames, which flows through the middle of London. In his pockets were the letters the lawyers had written to John Harmon, and there seemed no doubt that the unfortunate young man had been murdered and his body thrown into the river.

The night the body was found, while it lay at the police station, a young man, very much excited, came and asked to see it. He would not tell who he was, and his whole appearance was most wild and strange. The police wondered, but they saw no reason to detain the stranger, so after looking at the body, he went away again very hastily.

A great stir was made about the case, and the police tried their best to discover the murderer, but they were unsuccessful. Then it occurred to them that there was something suspicious in the appearance of the young man that night. They tried to find him, but he seemed to have disappeared.

At last the fortune was turned over to Mr. Boffin, and all but a few people thought no more about the murder.

Now, it was not really true that John Harmon had been drowned. This is what had happened:[Pg 328]

The young man had come back to England unwillingly, though he was coming to such wealth. Having left his father so long before in anger, he hardly liked to touch the money. And he dreaded having to marry a young lady he had never seen, with whom all his life he might be most unhappy.

On the ship was a seaman about his own age whose face somewhat resembled his own. With this man Harmon became friendly and before the ship reached England he had told him his trouble and his dread. The other proposed that Harmon disguise himself in sailor\'s clothes, go into the neighborhood where Miss Bella Wilfer lived, and see if she was one whom he could love.

Now the man whom Harmon was thus trusting was a villain, who, while he had been listening to the other\'s story, had been planning a crime against him. He had made up his mind to kill Harmon, and, as he looked so much like him, to marry Bella himself and claim the fortune.

Near the docks where the ship came in was a sailors\' boarding-house owned by a riverman of bad reputation named "Rogue" Riderhood. Riderhood had once been the partner of Hexam, the man who found the floating body, but one day he was caught trying to rob............
