To a man of Butler's egregious vanity his trial was a glorious opportunity for displaying his intellectual gifts, such as they were. One who had known him in prison about this time describes him as a strange compound of vanity and envy, blind to his own faults and envious of the material advantages enjoyed by others. Self-willed and arrogant, he could bully or whine with equal effect. Despising men, he believed that if a man did not possess some requisite quality, he had only to ape it, as few would distinguish between the real and the sham.
But with all these advantages in the struggle for life, it is certain that Butler's defence would have been far less effective had be{sic} been denied all professional aid. As a matter of fact, throughout his trial Butler was being advised by three distinguished members of the New Zealand bar, now judges of the Supreme Court, who though not appearing for him in court, gave him the full benefit of their assistance outside it. At the same time Butler carried off the thing well. Where imagination was required, Butler broke down; he could not write sketches of life in prison; that was too much for his pedestrian intellect. But given the facts of a case, dealing with a transaction of which he alone knew the real truth, and aided by the advice and guidance of trained intellects, Butler was unquestionably clever and shrewd enough to make the best use of such advantages in meeting the case against him.
Thus equipped for the coming struggle, this high-browed ruffian, with his semi-intellectual cast of countenance, his jerky restless posturing, his splay-footed waddle, "like a lame Muscovy duck," in the graphic words of his gaol companion, stood up to plead for his life before the Supreme Court at Dunedin.
It may be said at the outset that Butler profited greatly by the scrupulous fairness shown by the Crown Prosecutor. Mr. Haggitt extended to the prisoner a degree of consideration and forbearance, justified undoubtedly towards an undefended prisoner. But, as we have seen, Butler was not in reality undefended. At every moment of the trial he was in communication with his legal advisers, and being instructed by them how to meet the evidence given against him. Under these circumstances the unfailing consideration shown him by the Crown Prosecutor seems almost excessive. From the first moment of the trial Butler was fully alive to the necessities of his situation. He refrained from including in his challenges of the jury the gentleman who was afterwards foreman; he knew he was all right, he said, because he parted his hair in the middle, a "softy," in fact. He did not know in all probability that one gentleman on the jury had a rooted conviction that the murder of the Dewars was the work of a criminal lunatic. There was certainly nothing in Butler's demeanour or behaviour to suggest homicidal mania.
The case against Butler rested on purely circumstantial evidence.
No new facts of importance were adduced at the trial. The stealing of Dewar's wages, which had been paid to him on the Saturday, was the motive for the murder suggested by the Crown. The chief facts pointing to Butler's guilt were: his conversation with Mallard and Bain previous to the crime; his demeanour after it; his departure from Dunedin; the removal of his moustache and the soles of his boots; his change of clothes and the bloodstains found upon them, added to which was his apparent inability to account for his movements on the night in question.
Such as the evidence was, Butler did little to shake it in cross-examination. His questions were many of them skilful and pointed, but on more than one occasion the judge intervened to save him from the danger common to all amateur cross-examiners, of not knowing when to stop. He was most successful in dealing with the medical witnesses. Butler had explained the bloodstains on his clothes as smears that had come from scratches on his hands, caused by contact with bushes. This explanation the medical gentlemen with good reason rejected. But they went further, and said that these stains might well have been caused by the spurting and spraying of blood on to the murderer as he struck his victims. Butler was able to show by the position of the bloodstains on the clothes that such an explanation was open to considerable doubt.
Butler's speech in his defence lasted six hours, and was a creditable performance. Its arrangement is somewhat confused and repetitious, some points are over-elaborated, but on the whole he deals very successfully with most of the evidence given against him and exposes the unquestionable weakness of the Crown case. At the outset he declared that he had taken his innocence for his defence. "I was not willing," he said, "to leave my life in the hands of a stranger. I was willing to incur all the disadvantages which the knowledge of the law might bring upon me. I was willing, also, to enter on this case without any experience whatever of that peculiarly acquired art of cross-examination. I fear I have done wrong. If I had had the assistance of able counsel, much more light would have been thrown on this case than has been." As we have seen, Butler enjoyed throughout his trial the informal assistance of three of the most able counsel in New Zealand, so that this heroic attitude of conscious innocence braving all dangers loses most of its force. Without such assistance his danger might have been very real.
A great deal of the evidence as to his conduct and demeanour at the time of the murder Butler met by acknowledging that it was he who had broken into Mr. Stamper's house on the Saturday morning, burgled it and set it on fire. His consciousness of guilt in this respect was, he said, quite sufficient to account for anything strange or furtive in his manner at that time. He was already known to the police; meeting Bain on the Saturday night, he felt more than ever sure that he was susspected{sic} of the robbery at Mr. Stamper's; he therefore decided to leave Dunedin as soon as possible. That night, he said, he spent wandering about the streets half drunk, taking occasional shelter from the pouring rain, until six o'clock on the Sunday morning, when he went to the Scotia Hotel. A more detailed account of his movements on the night of the Dewars' murder he did not, or would not, give.
When he comes to the facts of the murder and his theories as to the nature and motive of the crime—theories which he developed at rather unnecessary length for the purpose of his own defence—his speech is interesting. It will be recollected that on the discovery of the murder, a knife was found on the grass outside the house. This knife was not the property of the Dewars. In Butler's speech he emphasised the opinion that this knife had been brought there by the murderer: "Horrible though it may be, my conclusion is that he brought it with the intention of cutting the throats of his victims, and that, finding they lay in rather an untoward position, he changed his mind, and, having carried out the object with which he entered the house, left the knife and, going back, brought the axe with which he effected his purpose. What was the purpose of the murderer? Was it the robbery of Dewar's paltry wages? Was it the act of a tiger broken loose on the community? An act of pure wanton devilry? or was there some more reasonable explanation of this most atrocious crime?"
Butler rejected altogether the theory of ordinary theft. No thief of ambitious views, he said, would pitch upon the house of a poor journeyman butcher. The killing of the family appeared to him to be the motive: "an enemy hath done this." The murderer seems to have had a knowledge of the premises; he enters the house and does his work swiftly and promptly, and is gone. "We cannot know," Butler continues, "all the passages in the lives of the murdered man or woman. What can we know of the hundred spites and jealousies or other causes of malice which might have caused the crime? If you say some obscure quarrel, some spite or jealousy is not likely to have been the cause of so dreadful a murder, you cannot revert to the robbery theory without admitting a motive much weaker in all its utter needlessness and vagueness. The prominent feature of the murder, indeed the only feature, is its ruthless, unrelenting, determined vindictiveness. Every blow seemed to say, 'You shall die you shall not live.'"
Whether Butler were the murderer of the Dewars or not, the theory that represented them as having been killed for the purpose of robbery has its weak side all the weaker if Butler, a practical and ambitious criminal, were the guilty man.
In 1882, two years after Butler's trial, there appeared in a New Zealand newspaper, Society, published in Christchurch, a series of Prison "Portraits," written evidently by one who had himself undergone a term of imprisonment. One of the "Portraits" was devoted to an account of Butler. The writer had known Butler in prison. According to the story told him by Butler, the latter had arrived in Dunedin with a quantity of jewellery he had stolen in Australia. This jewellery he entrusted to a young woman for safe keeping. After serving his first term of two years' imprisonment in Dunedin, Butler found on his release that the young woman had married a man of the name of Dewar. Butler went to Mrs. Dewar and asked for the return of his jewellery; she refused to give it up. On the night of the murder he called at the house in Cumberland Street and made a last appeal to her, but in vain. He determined on revenge. During his visit to Mrs. Dewar he had had an opportunity of seeing the axe and observing the best way to break into the house. He watched the husband's return, and decided to kill him as well as his wife on the chance of obtaining his week's wages. With the help of the knife which he had found in the backyard of a hotel he opened the window. The husband he killed in his sleep, the woman waked with the first blow he struck her. He found the jewellery in a drawer rolled up in a pair of stockings. He afterwards hid it in a well-marked spot some half-hour before his arrest.
A few years after its appearance in Society, this account of Butler was reproduced in an Auckland newspaper. Bain, the detective, wrote a letter questioning the truth of the writer's statements. He pointed out that when Butler first came to Dunedin he had been at liberty only a fortnight before serving his first term of imprisonment, very little time in which to make the acquaintance of a woman and dispose of the stolen jewellery. He asked why, if Butler had hidden the jewellery just before his arrest, he had not also hidden the opera-glasses which he had stolen from Mr. Stamper's house. Neither of these comments is very convincing. A fortnight seems time enough in which a man of Butler's character might get to know a woman and dispose of some jewellery; while, if Butler were the murderer of Mr. Dewar as ............
