The same evening a remarkable interview took place in the lock-up at Waikouaiti between Butler and Inspector Mallard. Mallard, who had some reason for suspecting Butler, bearing in mind their recent conversation, told the prisoner that he would be charged with the murder in Cumberland Street. For a few seconds, according to Mallard, the prisoner seemed terribly agitated and appeared to be choking. Recovering himself somewhat, he said, "If for that, you can get no evidence against me; and if I am hanged for it, I shall be an innocent man, whatever other crimes I may have committed." Mallard replied, "There is evidence to convict you—the fire was put out." Butler than{sic} said that he would ask Mallard a question, but, after a pause, decided not to do so. Mallard, after examining Butler's clothes, told him that those were not the clothes in which he had left the Scotia Hotel. Butler admitted it, and said he had thrown those away in the North East Valley. Mallard alluded to the disappearance of the prisoner's moustache. Butler replied that he had cut it off on the road. Mallard noticed then the backs of Butler's hands were scratched, as if by contact with bushes. Butler seemed often on the point of asking questions, but would then stop and say "No, I won't ask you anything." To the constables who had arrested him Butler remarked, "You ought to remember me, because I could have shot you if I had wished." When Mallard later in the evening visited Butler again, the prisoner who was then lying down said, "I want to speak to you. I want to ask the press not to publish my career. Give me fair play. I suppose I shall be convicted and you will see I can die like a man."
A few days after Butler's arrest a ranger on the Town Belt, a hill overlooking Dunedin, found a coat, a hat and silk striped cravat, and a few days later a pair of trousers folded up and placed under a bush. These articles of clothing were identified as those which Butler had been seen wearing on the Saturday and Sunday morning. They were examined. There were a number of bloodstains on them, not one of them larger in size than a pea, some almost invisible. On the front of the trousers about the level of the groin there were blood spots on both sides. There was blood on the fold of the left breast of the coat and on the lining of the cuff of the right arm. The shirt Butler was wearing at the time of his arrest was examined also. There were small spots of blood, about fourteen altogether, on the neck and shoulder bands, the right armpit, the left sleeve, and on both wristbands. Besides the clothes, a salmon tin was found on the Town Belt, and behind a seat in the Botanical Gardens, from which a partial view of the Dewars' house in Cumberland Street could be obtained, two more salmon tins were found, all three similar to the five purchased by Butler on the Sunday morning, two of which had been in his possession at the time of his arrest.
Such were the main facts of the case which Butler had to answer when, a few weeks later, he was put on his trial before the Supreme Court at Dunedin. The presiding judge was Mr. Justice Williams, afterwards Sir Joshua Williams and a member of the Privy Council. The Crown Prosecutor, Mr. Haggitt, conducted the case for the Crown, and Butler defended himself.
II THE TRIAL OF BUTLER
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.
