Miller followed his orders to the letter, and the stipend was increased to the munificent sum of forty dollars per month.
Meantime the case against Ammon languished and the District Attorney of New York County was at his wits' end to devise a means to procure the evidence to convict him. To do this it would be necessary to establish affirmatively that the thirty thousand five hundred dollars received by Ammon from Miller and deposited with Wells, Fargo & Co. was the identical money stolen by Miller from the victims of the Franklin Syndicate. It was easy enough to prove that Miller stole hundreds of thousands of dollars, that Ammon received hundreds of thousands, but you had to prove that the same money stolen by Miller passed to the hands of Ammon. Only one man in the world, as Ammon had foreseen, could supply this last necessary link in the chain of evidence and he was a convict—and mute.
It now became the task of the District Attorney to induce Miller to confess the truth and take the stand against Ammon. He had been in prison a considerable time and his health was such as to necessitate his being transferred to the hospital ward. Several of the District Attorney's assistants visited him at various times at Sing Sing in the hope of being able to persuade him to turn State's evidence, but all their efforts were in vain. Miller refused absolutely to say anything that would tend to implicate Ammon.
At last the District Attorney himself, accompanied by Mr. Nott, who later prosecuted Ammon, made a special trip to Sing Sing to see what could be done. They found Miller lying upon his prison pallet, his harsh cough and blazing eyes speaking only too patently of his condition. At first Mr. Nott tried to engage him in conversation while the District Attorney occupied himself with other business in another part of the ward, but it was easily apparent that Miller would say nothing. The District Attorney then approached the bed where Miller was lying and inquired if it were true that he declined to say anything which might tend to incriminate Ammon. After some hesitation Miller replied that, even if he should testify against his old accomplice, there was nothing to show that he would be pardoned, and that he would not talk unless he had actually in his hands some paper or writing which would guarantee that if he did so he would be set free.
The spectacle of a convicted felon haggling with an officer of the law over the terms upon which he would consent to avail himself of an opportunity to make the only reparation still possible angered the District Attorney, and, turning fiercely upon the prisoner, he arraigned him in scathing terms, stating that he was a miserable swindler and thief, who had robbed thousands of poor people of all the money they had in the world, that he showed himself devoid of every spark of decency or repentance by refusing to assist the law in punishing his confederate and assisting his victims in getting back what was left of the money, and that he, the District Attorney, felt himself humiliated in having consented to come there to visit and talk with such a heartless and depraved specimen of humanity. The District Attorney then turned his back upon Miller, whose eyes filled with tears, but who made no response.
A few moments later the convict asked permission to speak to the District Attorney alone. With some reluctance the latter granted the request and the others drew away.
"Mr. District Attorney," said the wretched man in a trembling voice, with the tears still suffusing his eyes, "I am a thief; I did rob all those poor people, and I am heartily sorry for it. I would gladly die, if by doing so I could pay them back. But I haven't a single cent of all the money that I stole and the only thing that stands between my wife and baby and starvation is my keeping silence. If I did what you ask, the only money they have to live on would be stopped. I can't see them starve, glad as I would be to do what I can now to make up for the wrong I have done."
The District Attorney's own eyes were not entirely dry as he held out his hand to Miller.
"Miller," he replied, "I have done you a great injustice. I honor you for the position you have taken. Were I in your place I should probably act exactly as you are doing. I cannot promise you a pardon if you testify against Ammon. I cannot even promise that your wife will receive forty dollars a month, for the money in my charge cannot be used for such a purpose; all I can assure you of is that, should you decide to help me, a full and fair statement of all you may have done will be sent to the Governor with a request that he act favorably upon any application for a pardon which you may make. The choice must be your own. Whatever you decide to do, you have my respect and sympathy. Think well over the matter. Do not decide at once; wait for a day or two, and I will return to New York and you can send me word."
The next day Miller sent word that he had determined to tell the truth and take the stand, whatever the consequences to himself and his family might be. He was immediately transferred to the Tombs Prison in New York City, where he made a complete and full confession, not only assisting in every way in securing evidence for the prosecution of Ammon, but aiding his trustee in bankruptcy to determine the whereabouts of some sixty thousand dollars of the stolen money, which but for him would never have been recovered. At the same time Ammon was re-arrested upon a bench warrant, and his bail sufficiently increased to render his appearance for trial probable. As Miller had foreseen, the monthly payment to his wife instantly stopped.
