After these arrangements we separated, George and I following to ascertain if he was being watched or shadowed by detectives. When he entered the hotel we remained in view of the entrance. It was not long before he reappeared and walked leisurely along the street. A few seconds after we saw another man come out, cross the street, and go in the same direction. I followed him, and was soon satisfied that he was keeping Mac in view. This sort of double hunt was kept up until dusk, when Mac returned to his hotel, unconscious that a moment later his "shadow" entered the place also. Here was a complication, indeed, though it was no more than we had anticipated among the possibilities; still, I had indulged in the hope that the bank would rely entirely upon the passport system, and take no further steps for a day or two, which was all the time required to carry out our plan. Though Mac had good nerve, it was already somewhat shaken, and surely the situation would have unnerved most men. Therefore, fearing that the certain knowledge of imminent danger might still further confuse him and cause some false move, we determined to keep our discovery to ourselves. George next proceeded to an obscure part of the town, and stopping at a small but respectable looking tavern, he engaged a room for the next day, also a carriage, with an English-speaking driver, to be in readiness at 3 o'clock the next morning. Promptly at the hour he was at the livery stable, where he found the carriage ready, and was driven to the Hotel d'Europe. Sending the driver up to the office on the second floor, Mac soon appeared and informed him that he had promised to take to the station a man who was stopping at the hotel. "He is going to S. Romao by the same train," continued Mac, "and seems a good fellow, for I had a long talk with him last night." Upon seeing signs of disapproval in my face, he explained: "Well, you know, he said he could not get a carriage at so early an hour in the morning, and I thought it could do no harm to take him in, and he is waiting upstairs." Here I joined them, and it would be difficult for the reader to imagine the effect of this surprising communication upon our minds, for it was clear enough that this was the very person who had been "shadowing" Mac the day before, and had skillfully ingratiated himself into his new friend's confidence. I could but admire his nerve in asking a contemplated victim for a ride to the station. I said to Mac: "What in the world can you be thinking of? Don't you see you are blocking our whole plan? Go up and tell him your carriage is loaded down with luggage, and express your regrets that you cannot accommodate him." During this time the baggage was being placed in the carriage, and as soon as Mac had dismissed his "passenger," who for some reason did not show himself, we started rapidly for the station. On the way I requested him to avoid making any new friends until he should find himself well out at sea. I said:
