Having developed to the jury his theory of why the crime was committed, Butler told them that, as far as he was concerned, there were four points against him on which the Crown relied to prove his guilt. Firstly, there was the fact of his being in the neighbourhood of the crime on the Sunday morning; that, he said, applied to scores of other people besides himself. Then there was his alleged disturbed appearance and guilty demeanour. The evidence of that was, he contended, doubtful in any case, and referable to another cause; as also his leaving Dunedin in the way and at the time he did. He scouted the idea that murderers are compelled by some invisible force to betray their guilt. "The doings of men," he urged, "and their success are regulated by the amount of judgment that they possess, and, without impugning or denying the existence of Providence, I say this is a law that holds good in all cases, whether for evil or good. Murderers, if they have the sense and ability and discretion to cover up their crime, will escape, do escape, and have escaped. Many people, when they have gravely shaken their heads and said 'Murder will out,' consider they have done a great deal and gone a long way towards settling the question. Well, this, like many other stock formulas of Old World wisdom, is not true. How many murders are there that the world has never heard of, and never will? How many a murdered man, for instance, lies among the gum-trees of Victoria, or in the old abandoned mining-shafts on the diggings, who is missed by nobody, perhaps, but a pining wife at home, or helpless children, or an old mother? But who were their murderers? Where are they? God knows, perhaps, but nobody else, and nobody ever will." The fact, he said, that he was alleged to have walked up Cumberland Street on the Sunday morning and looked in the direction of the Dewars' house was, unless the causes of superstition and a vague and incomplete reasoning were to be accepted as proof, evidence rather of his innocence than his guilt. He had removed the soles of his boots, he said, in order to ease his feet in walking; the outer soles had become worn and ragged, and in lumps under his feet. He denied that he had told Bain, the detective, that he would break out as a desperate tiger let loose on the community; what he had said was that he was tired of living the life of a prairie dog or a tiger in the jungle.

Butler was more successful when he came to deal with the bloodstains on his clothes. These, he said, were caused by the blood from the scratches on his hands, which had been observed at the time of his arrest. The doctors had rejected this theory, and said that the spots of blood had been impelled from the axe or from the heads of the victims as the murderer struck the fatal blow. Butler put on the clothes in court, and was successful in showing that the position and appearance of certain of the blood spots was not compatible with such a theory. "I think," he said, "I am fairly warranted in saying that the evidence of these gentlemen is, not to put too fine a point on it, worth just nothing at all."

Butler's concluding words to the jury were brief but emphatic: "I stand in a terrible position. So do you. See that in your way of disposing of me you deliver yourselves of your responsibilities."

In the exercise of his forbearance towards an undefended prisoner, Mr. Haggitt did not address the jury for the Crown. At four o'clock the judge commenced his summing-up. Mr. Justice Williams impressed on the jury that they must be satisfied, before they could convict the prisoner, that the circumstances of the crime and the prisoner's conduct were inconsistent with any other reasonable hypothesis than his guilt. There was little or no evidence that robbery was the motive of the crime. The circumstance of the prisoner being out all Saturday night and in the neighbourhood of the crime on Sunday morning only amounted to the fact that he had an opportunity shared by a great number of other persons of committing the murder. The evidence of his agitation and demeanour at the time of his arrest must be accepted with caution. The evidence of the blood spots was of crucial importance; there was nothing save this to connect him directly with the crime. The jury must be satisfied that the blood on the clothes corresponded with the blood marks which, in all probability, would be found on the person who committed the murder. In regard to the medical testimony some caution must be exercised. Where medical gentlemen had made observations, seen with their own eyes, the direct inference might be highly trustworthy, but, when they proceeded to draw further inferences, they might be in danger of looking at facts through the spectacles of theory; "we know that people do that in other things besides science—politics, religion, and so forth." Taking the Crown evidence, at its strongest, there was a missing link; did the evidence of the bloodstains supply it? These bloodstains were almost invisible. Could a person be reasonably asked to explain how they came where they did? Could they be accounted for in no other reasonable way than that the clothes had been worn by the murderer of the Dewars?

In spite of a summing-up distinctly favourable to the prisoner, the jury were out three hours. According to one account of their proceedings, told to the writer, there was at first a majority of the jurymen in favour of conviction. But it was Saturday night; if they could not come to a decision they were in danger of being locked up over Sunday. For this reason the gentleman who held an obstinate and unshaken belief that the crime was the work of a homicidal maniac found an unexpected ally in a prominent member of a church choir who was down to sing a solo in his church on Sunday, and was anxious not to lose such an opportunity for distinction. Whatever the cause, after three hours' deliberation the jury returned a verdict of "Not Guilty." Later in the Session Butler pleaded guilty to the burglary at Mr. Stamper's house, and was sentenced to eighteen years' imprisonment. The severity of this sentence was not, the judge said, intended to mark the strong suspicion under which Butler laboured of being a murderer as well as a burglar.

The ends of justice had been served by Butler's acquittal. But in the light of after events, it is perhaps unfortunate that the jury did not stretch a point and so save the life of Mr. Munday of Toowong. Butler underwent his term of imprisonment in Littleton Jail. There his reputation was most unenviable. He is described by a fellow prisoner as ill-tempered, malicious, destructive, but cowardly and treacherous. He seems to have done little or no work; he looked after the choir and the library, but was not above breaking up the one and smashing the other, if the fit seized him.

III HIS DECLINE AND FALL

In 1896 Butler was released from prison. The news of his release was described as falling like a bombshell among the peaceful inhabitants of Dunedin. In the colony of Victoria, where Butler had commenced his career, it was received with an apprehension that was justified by subsequent events. It was believed that on his release the New Zealand authorities had shipped Butler off to Rio. But it was not long before he made his way once more to Australia. From the moment of his arrival in Melbourne he was shadowed by the police. One or two mysterious occurrences soon led to his arrest. On June 5 he was sentenced to twelve months' imprisonment under the Criminal Influx Act, which makes it a penal offence for any convict to enter Victoria for three years after his release from prison. Not content with this, the authorities determined to put Butler on trial on two charges of burglary and one of highway robbery, committed since his return to the colony. To one charge of burglary, that of breaking into a hairdresser's shop and stealing a wig, some razors and a little money, Butler pleaded guilty.

But the charge of highway robbery, which bore a singular resemblance to the final catastrophe in Queensland, he resisted to the utmost, and showed that his experience in the Supreme Court at Dunedin had not been lost on him. At half-past six one evening in a suburb of Melbourne an elderly gentleman found himself confronted by a bearded man, wearing a long overcoat and a boxer hat and flourishing a revolver, who told him abruptly to "turn out his pockets." The old man did ashe was told. The robber then asked for his watch and chain, saying "Business must be done." The old gentleman mildly urged that this was a dangerous business. On being assured that the watch was a gold one, the robber appeared willing to risk the danger, and departed thoroughly satisfied. The old gentleman afterwards identified Butler as the man who had taken his watch. Another elderly man swore that he had seen Butler at the time of the robbery in the possession of a fine gold watch, which he said had been sent him from home. But the watch had not been found in Butler's possession.

On June 18 Butler was put on his trial in the Melbourne Criminal Court before Mr. Justice Holroyd, charged with robbery under arms. His appearance in the dock aroused very considerable interest. "It was the general verdict," wrote one newspaper, "that his intellectual head and forehead compared not unfavourably with those of the judge." He was decently dressed and wore pince-nez, which he used in the best professional manner as he referred to the various documents that lay in front of him. He went into the witness-box and stated that the evening of the crime he had spent according to his custom in the Public Library.
