Dr Teesdale was a bachelor and a man of independent means, and lived in a tall-windowed and commodious house in Bedford Square, where a plain cook of surpassing excellence looked after his food, and her husband his person. There was no need for him to practise a profession at all, and he performed his work at the prison for the sake of the study of the minds of criminals. Most crime – the transgression, that is, of the rule of conduct which the human race has framed for the sake of its own preservation – he held to be either the result of some abnormality of the brain or of starvation. Crimes of theft, for instance, he would by no means refer to one head; often it is true they were the result of actual want, but more often dictated by some obscure disease of the brain. In marked cases it was labelled as kleptomania, but he was convinced there were many others which did not fall directly under dictation of physical need. More especially was this the case where the crime in question involved also some deed of violence, and he mentally placed underneath this heading, as he went home that evening, the criminal at whose last moments he had been present that morning. The crime had been abominable, the need of money not so very pressing, and the very abomination and unnaturalness of the murder inclined him to consider the murderer as lunatic rather than criminal. He had been, as far as was known, a man of quiet and kindly disposition, a good husband, a sociable neighbour. And then he had committed a crime, just one, which put him outside all pales. So monstrous a deed; whether perpetrated by a sane man or a mad one, was intolerable; there was no use for the doer of it on this planet at all. But somehow the doctor felt that he would have been more at one with the execution of justice, if the dead man had confessed. It was morally certain that he was guilty, but he wished that when there was no longer any hope for him he had endorsed the verdict himself.
