'Go.'

That was all, and there was nothing mysterious about the syllable, for almost any one would understand that it was used as in starting a footrace, and meant, 'Begin operations at once!' It was the word agreed upon between Isidore Bamberger and his lawyer. The latter had been allowed all the latitude required in such a case, for he had instructions to lay the evidence before the District Attorney-General without delay, if anything happened to make immediate action seem advisable. In any event, he was to do so on receiving the message which had now been sent.

The evidence consisted, in the first place, of certain irrefutable proofs that Miss Bamberger had not died from shock, but had been killed by a thin and extremely sharp instrument with which she had been stabbed in the back. Isidore Bamberger's own doctor had satisfied himself of this, and had signed his statement under oath, and Bamberger had instantly thought of a certain thin steel letter-opener which Van Torp always had in his pocket.

Next came the affidavit of Paul Griggs. The witness knew the Opera House well. Had been in the stalls on the night in question. Had not moved from his seat till the performance was over, and had been one of the last to get out into the corridor. There was a small door in the corridor on the south side which was generally shut. It opened upon a passage communicating with the part of the building that is let for business offices. Witness's attention had been attracted by part of a red silk dress which lay on the floor outside the door, the latter being ajar. Suspecting an accident, witness opened door, found Miss Bamberger, and carried her to manager's room not far off. On reaching home had found stains of blood on his hands. Had said nothing of this, because he had seen notice of the lady's death from shock in next morning's paper. Was nevertheless convinced that blood must have been on her dress.

The murder was therefore proved. But the victim had not been robbed of her jewellery, which demonstrated that, if the crime had not been committed by a lunatic, the motive for it must have been personal.

With regard to identity of the murderer, Charles Feist deposed that on the night in question he had entered the Opera late, having only an admission to the standing room, that he was close to one of the doors when the explosion took place and had been one of the first to leave the house. The emergency lights in the corridors were on a separate circuit, but had been also momentarily extinguished. They were up again before those in the house. The crowd had at once become jammed in the doorways, so that people got out much more slowly than might have been expected. Many actually fell in the exits and were trampled on. Then Madame Cordova had begun to sing in the dark, and the panic had ceased in a few seconds. The witness did not think that more than three hundred people altogether had got out through the several doors. He himself had at once made for the main entrance. A few persons rushed past him in the dark, descending the stairs from the boxes. One or two fell on the steps. Just as the emergency lights went up again, witness saw a young lady in a red silk dress fall, but did not see her face distinctly; he was certain that she had a short string of pearls round her throat. They gleamed in the light as she fell. She was instantly lifted to her feet by Mr. Rufus Van Torp, who must have been following her closely. She seemed to have hurt herself a little, and he almost carried her down the corridor in the direction of the carriage lobby on the Thirty-Eighth Street side. The two then disappeared through a door. The witness would swear to the door, and he described its position accurately. It seemed to have been left ajar, but there was no light on the other side of it. The witness did not know where the door led to. He had often wondered. It was not for the use of the public. He frequently went to the Opera and was perfectly familiar with the corridors. It was behind this door that Paul Griggs had found Miss Bamberger. Questioned as to a possible motive for the murder, the witness stated that Rufus Van Torp was known to have shown homicidal tendencies, though otherwise perfectly sane. In his early youth he had lived four years on a cattle-ranch as a cow-puncher, and had undoubtedly killed two men during that time. Witness had been private secretary to his partner, Mr. Isidore Bamberger, and while so employed Mr. Van Torp had fired a revolver at him in his private office in a fit of passion about a message witness was sent to deliver. Two clerks in a neighbouring room had heard the shot. Believing Mr. Van Torp to be mad, witness had said nothing at the time, but had left Mr. Bamberger soon afterwards. It was always said that, several years ago, on board of his steam yacht, Mr. Van Torp had once violently pulled a friend who was on board out of his berth at two in the morning, and had dragged him on deck, saying that he must throw him overboard and drown him, as the only way of saving his soul. The watch on deck had had great difficulty in overpowering Mr. Van Torp, who was very strong. With regard to the late Miss Bamberger the witness thought that Mr. Van Torp had killed her to get rid of her, because she was in possession of facts that would ruin him if they were known and because she had threatened to reveal them to her father. If she had done so, Van Torp would have been completely in his partner's power. Mr. Bamberger could have made a beggar of him as the only alternative to penal servitude. Questioned as to the nature of this information, witness said that it concerned the explosion, which had been planned by Van Torp for his own purposes. Either in a moment of expansion, under the influence of the drug he was in the habit of taking, or else in real anxiety for her safety, he had told Miss Bamberger that the explosion would take place, warning her to remain in her home, which was situated on the Riverside Drive, very far from the scene of the disaster. She had undoubtedly been so horrified that she had thereupon insisted upon dissolving her engagement to marry him, and had threatened to inform her father of the horrible plot. She had never really wished to marry Van Torp, but had accepted him in deference to her father's wishes. He was known to be devoting himself at that very time to a well-known primadonna engaged at the Metropolitan Opera, and Miss Bamberger probably had some suspicion of this. Witness said the motive seemed sufficient, considering that the accused had already twice taken human life. His choice lay between killing her and falling into the power of his partner. He had injured Mr. Bamberger, as was well known, and Mr. Bamberger was a resentful man.

The latter part of Charles Feist's deposition was certainly more in the nature of an argument than of evidence pure and simple, and it might not be admitted in court; but Isidore Bamberger had instructed his lawyer, and the Public Prosecutor would say it all, and more also, and much better; and public opinion was roused all over the United States against the Nickel Tyrant, as Van Torp was now called.

In support of the main point there was a short note to Miss Bamberger in Van Torp's handwriting, which had afterwards been found on her dressing-table. It must have arrived before she had gone out to dinner. It contained a final and urgent entreaty that she would not go to the Opera, nor leave the house that evening, and was signed with Van Torp's initials only, but no one who knew his handwriting would be likely to doubt that the note was genuine.

There were some other scattered pieces of evidence which fitted the rest very well. Mr. Van Torp had not been seen at his own house, nor in any club, nor down town, after he had gone out on Wednesday afternoon, until the following Friday, when he had returned to make his final arrangements for sailing the next morning. Bamberger had employed a first-rate detective, but only one, to find out all that could be discovered about Van Torp's movements. The millionaire had been at the house on Riverside Drive early in the afternoon to see Miss Bamberger, as he had told Margaret on board the steamer, but Bamberger had not seen his daughter after that till she was brought home dead, for he had been detained by an important meeting at which he presided, and knowing that she was dining out to go to the theatre he had telephoned that he would dine at his club. He himself had tried to telephone to Van Torp later in the evening but had not been able to find him, and had not seen him till Friday.

This was the substance of the evidence which Bamberger's lawyer and the detective would lay before the District Attorney-General on receiving the cable.
