He therefore cabled to his office in New York particulars as to Mac's departure, and then he turned all his attention to discovering who this F.A. Warren could be. Mac had cabled Irving that he was coming by the Thuringia. Pinkerton, feeling that there was no secrecy required about his man being on the steamer, gave the fact to the press, and Irving discovered, very much to his chagrin, that all the world shared with him his secret as to Mac's whereabouts, and that if he would save his reputation he would have to be on hand, not as a friend and confederate, but in his official capacity and make a genuine arrest—that is, unless he could arrange to have Mac taken off the steamer in a small boat as soon as she came into the lower bay and before the police boat, with its load of officials, came alongside. This Irving and his two subordinates resolved to attempt, so he took into his counsels a great chum of his and a well-known burglar by the name of Johnny Dobbs. To him was given the job of getting Mac off the steamer, but he made a serious blunder. Instead of hiring and manning two boats, one to relieve the other, he got only one. For a day or two they came within hailing distance of all incoming steamers, but were ashore on Staten Island, taking a rest, when bright and early one morning the Thuringia slipped into the harbor. There was a man in the boat with Dobbs who knew Mac, and the plan was to meet the steamer, and as Mac was sure to be on deck on the lookout, to shout to him to jump overboard and they would pick him up and make for shore. Once ashore and warned they would not have seen him again.
After the Thuringia came into the harbor, Irving kept the police boat waiting over an hour. Then, supposing his friend was safe ashore, he boarded the ship. There were five United States Marshals on the police tug, the bank lawyers and some of the private inquiry officials.
Irving, accompanied by White and Stanley, jumped aboard the big ship, after giving orders to the captain of the tug not to let any one off until he gave permission. Mac saw the tug and recognized his three friends, but was in no way alarmed until Irving, shaking hands with him, hurriedly explained the state of affairs. Mac took them to his cabin and gave them $150,000 in bonds, $10,000 in greenbacks, which he had bought of the brokers in London, besides English bank notes and two or three valuable diamonds. Then taking out several bags of sovereigns he said: "Now, boys, help yourselves. Load yourselves down and keep them from the enemy." What a picture those fellows loading up with that golden store of sovereigns would have made! They knew the marshals and detectives they held entrapped aboard the tug would be furious, and morally sure that Irving & Co. had plucked their bird. Therefore any appearance of pockets bulging out might lead to disgrace, so, while they hated to leave any, for their fingers itched for all, yet they were forced to that cruel self-denial.
One amusing piece of impudence on Irving's part occurred when looking with greedy eyes on the eight-carat diamond Mac wore on his finger, he said: "My God, Mac, I wish I had brought along a paste diamond. You could wear the ring and give me yours in exchange." The ring having been seen by so many he feared to chance taking it. No doubt his enforced denial for long sat heavy on Jimmy's soul. What a penchant all our honest detectives have for gems, and where do they get them?
In the mean time a storm was raging among the rival officers, who did not relish being duped, and finally by threats forced the captain to bring the tug alongside the steamer. Then they rushed on board to find Irving & Co. with their prisoner awaiting them.
The marshals went to the cabin and found some £4,000 or £5,000 in sovereigns, but when Mac was searched nothing was found on him but $20 in greenbacks. He was turned over to the United States officials and landed in Ludlow Street Jail, pending an examination before the United States Commissioner with a view to his extradition.
How the Pinkertons unearthed the $254,000 wrapped in old clothing in Mac's trunk at the European Express Office, 44 Broadway, would take too much time to tell here, or how circulars were sent out to the banks and trust companies warning them to hold all funds deposited by any of our party, or how Pinkerton and his men recovered large sums in various places, must all be passed over here. Suffice it to say that the fatal piece of blotting paper was produced in New York along with many lesser points of evidence, and after a hard legal fight Mac was finally ordered to be given up to the English Government to stand his trial for complicity in the great bank forgery.
The legal proceedings before the commissioner lasted three full months. The array of counsel on both sides made it a forensic contest between giants, in which all past history was invoked for precedents. This extradition case attracted wide attention.
After United States Commissioner Gutman had finally decided to surrender him to the demand of the British Government, appeal was made to the United States Circuit Court, Judge Woodruff, then to the Supreme Court, Judge Barrett, before whom Mac was brought by writs of habeas corpus; but the commissioner's decision was sustained. Mac was sent to Fort Columbus for safe-keeping while counsel were vainly arguing on new writs of habeas corpus and certiorari, but before any conclusion could be reached, he was hurried away by his custodians. He had scarcely time to bid good-bye to his counsel, when with a United States officer he was hurried into a carriage in Chambers street, guarded by Chief Deputy Marshal Kennedy and Deputies Robinson and Crowley, and driven rapidly down Broadway to the Battery, so that the large crowd who gathered to witness his departure from the metropolis had very little time to feast their eyes.
He was transferred from the Battery to Governor's Island by a tugboat and subsequently handed over by the deputy marshals to the charge of Major J. P. Roy, who had him escorted to Fort Columbus.
