When he was in the narrow alley he stopped again and laughed, without making any sound, so heartily that he had to stand still till the fit passed; and the expression of his unhealthy face just then would have disturbed even Mr. Bamberger, who knew him well.

But Mr. Bamberger was sitting in the easy-chair before the fireplace, and his eyes were fixed on the bright point at which the shiny copper kettle reflected the gaslight. His head had fallen slightly forward, so that his bearded chin was out of sight below the collar of his overcoat, leaving his eagle nose and piercing eyes above it. He was like a bird of prey looking down over the edge of its nest. He had not taken off his hat for Mr. Feist, and it was pushed back from his bony forehead now, giving his face a look that would have been half comic if it had not been almost terrifying: a tall hat set on a skull, a little back or on one side, produces just such an effect.

There was no moisture in the keen eyes now. In the bright spot on the copper kettle they saw the vision of the end towards which he was striving with all his strength, and all his heart, and all his wealth. It was a grim little picture, and the chief figure in it was a thick-set man who had a queer cap drawn down over his face and his hands tied; and the eyes that saw it were sure that under the cap there were the stony features of a man who had stolen his friend's wife and killed his friend's daughter, and was going to die for what he had done.

Then Isidore Bamberger's right hand disappeared inside the breast of his coat and closed lovingly upon a full pocket-book; but there was only a little money in it, only a few banknotes folded flat against a thick package of sheets of notepaper all covered with clear, close writing, some in ink and some in pencil; and if what was written there was all true, it was enough to hang Mr. Rufus Van Torp.

There were other matters, too, not written there, but carefully entered in the memory of the injured man. There was the story of his marriage with a beautiful, penniless girl, not of his own faith, whom he had taken in the face of strong opposition from his family. She had been an exquisite creature, fair and ethereal, as degenerates sometimes are; she had cynically married him for his money, deceiving him easily enough, for he was willing to be blinded; but differences had soon arisen between them, and had turned to open quarrelling, and Mr. Van Torp had taken it upon himself to defend her and to reconcile them, using the unlimited power his position gave him over his partner to force the latter to submit to his wife's temper and caprice, as the only alternative to ruin. Her friendship for Van Torp grew stronger, till they spent many hours of every day together, while her husband saw little of her, though he was never altogether estranged from her so long as they lived under one roof.

But the time came at last when Bamberger had power too, and Van Torp could no longer hold him in check with a threat that had become vain; for he was more than indispensable, he was a part of the Nickel Trust, he was the figure-head of the ship, and could not be discarded at will, to be replaced by another.

As soon as he was sure of this and felt free to act, Isidore Bamberger divorced his wife, in a State where slight grounds are sufficient. For the sake of the Nickel Trust Van Torp's name was not mentioned. Mrs. Bamberger made no defence, the affair was settled almost privately, and Bamberger was convinced that she would soon marry Van Torp. Instead, six weeks had not passed before she married Senator Moon, a man whom her husband had supposed she scarcely knew, and to Bamberger's amazement Van Torp's temper was not at all disturbed by the marriage. He acted as if he had expected it, and though he hardly ever saw her after that time, he exchanged letters with her during nearly two years.

Bamberger's little daughter Ida had never been happy with her beautiful mother, who had alternately spoilt her and vented her temper on her, according to the caprice of the moment. At the time of the divorce the child had been only ten years old; and as Bamberger was very kind to her and was of an even disposition, though never very cheerful, she had grown up to be extremely fond of him. She never guessed that he did not love her in return, for though he was cynical enough in matters of business, he was just according to his lights, and he would not let her know that everything about her recalled her mother, from her hair to her tone of voice, her growing caprices, and her silly fits of temper. He could not believe in the affection of a daughter who constantly reminded him of the hell in which he had lived for years. If what Van Torp told Lady Maud of his own pretended engagement to Ida was true, it was explicable only on that ground, so far as her father was concerned. Bamberger felt no affection for his daughter, and saw no reason why she should not be used as an instrument, with her own consent, for consolidating the position of the Nickel Trust.

As for the former Mrs. Bamberger, afterwards Mrs. Moon, she had gone to Europe in the autumn, not many months after her marriage, leaving the Senator in Washington, and had returned after nearly a year's absence, bringing her husband a fine little girl, whom she had christened Ida, like her first child, without consulting him. It soon became apparent that the baby was totally deaf; and not very long after this discovery, Mrs. Moon began to show signs of not being quite sane. Three years later she was altogether out of her mind, and as soon as this was clear the child was sent to the East to be taught. The rest has already been told. Bamberger, of course, had never seen little Ida, and had perhaps never heard of her existence, and Senator Moon did not see her again before he died.

Bamberger had not loved his own daughter in her life, but since her tragic death she had grown dear to him in memory, and he reproached himself unjustly with having been cold and unkind to her. Below the surface of his money-loving nature there was still the deep and unsatisfied sentiment to which his wife had first appealed, and by playing on which she had deceived him into marrying her. Her treatment of him had not killed it, and the memory of his fair young daughter now stirred it again. He accused himself of having misunderstood her. What had been unreal and superficial in her mother had perhaps been true and deep in her. He knew that she had loved him; he knew it now, and it was the recollection of that one being who had been devoted to him for himself, since he had been a grown man, that sometimes brought the tears from his eyes when he was alone. It would have been a comfort, now, to have loved her in return while she lived, and to have trusted in her love then, instead of having been tormented by the belief that she was as false as her mother had been.
