Matt could not make out how much he really meant by saying that Northwick could be defended very fairly on the ground of insanity; and that he would enjoy managing such a defence. It was a common thing to show that a murderer was insane; why not a defaulter? Tilted back in his chair, with one leg over the corner of his table, and changing the tobacco in his mouth from one cheek to the other as he talked, the lawyer outlined the argument which he said could be made very effective. There was the fact to begin with, that Northwick was a very wealthy man, and had no need of more money when he began to speculate; Putney held that this want of motive could be made a strong point; and that the reckless, almost open, way in which Northwick used the company's money, when he began to borrow, was proof in itself of unsound mind: apparently he had no sense whatever of _meum_ and _tuum_, especially _tuum_. Then, the total collapse of the man when he was found out; his flight without an effort to retrieve himself, although his shortage was by no means hopelessly vast, and could have been almost made up by skilful use of the credit that Northwick could command, was another evidence of shaken reason. But besides all this, there was his behavior since he left home. He had been absent nearly five months, and in that time he had made no attempt whatever to communicate with his family, although he must have known that it was perfectly safe for him to do so. He was a father who was almost dotingly fond of his children, and singularly attached to his home; yet he had remained all that time in voluntary exile, and he had left them in entire uncertainty as to his fate except so far as they could accept the probability of his death by a horrible casualty. This inversion of the natural character of a man was one of the most striking phenomena of insanity, and Putney, for the purpose of argument, maintained that it could be made to tell tremendously with a jury. Matt was unable to enjoy the sardonic metaphysics of the case with Putney. He said gravely that he had been talking of the matter with Dr. Morrell, and he had no doubt that there was a taint of insanity in every wrong-doer; some day he believed the law would take cognizance of the fact. "I don't suppose the time is quite ripe yet, though I think I could make out a strong case for Brother Northwick," said Putney. He seemed to enter into it more fully, as if he had a mischievous perception of Matt's uneasiness, and chose to torment him; but then apparently he changed his mind, and dealt with other aspects of their common interest so seriously and sympathetically, that Matt parted from him with a regret that he could not remove the last barrier between them, and tell the lawyer that he concerned himself so anxiously in the affairs of that wretched defaulter because his dearest hope was that the daughter of the criminal would some day be his wife.
