I now glanced over my force to see who was the best person to select for a "shadow". Porter had been promoted by me to be a sort of "roper". Most people may suppose that nearly any one can perform the duties of a "shadow", and that it is the easiest thing in the world to follow up a man; but such is not the case. A "shadow" has a most difficult position to maintain. It will not do to follow a person on the opposite side of the street, or close behind him, and when he stops to speak to a friend stop also; or if a person goes into a saloon, or store, pop in after him, stand staring till he goes out, and then follow him again. Of course such a "shadow" would be detected in fifteen minutes. Such are not the actions of the real "shadow", or, at least, of the "shadow" furnished by my establishment. I had just the man for the place, in Mr. Roch, who could follow a person for any length of time, and never be discovered. Having settled on Roch as the proper man for the position, I summoned him to my private office. Roch was a German. He was about forty-five years old, of spare appearance and rather sallow or tanned complexion. His nose was long, thin and peaked, eyes clear but heavy looking, and hair dark. He was slightly bald, and though he stooped a little, was five feet ten inches in height. He had been in my employ for many years, and I knew him thoroughly, and could trust him. I informed him of the duties he was to perform, and gave him minute instructions how he was to act. He was to keep out of sight as much as possible in Montgomery. Porter would manage to see him on his arrival, unknown to any one there, and would point out to him Maroney and his wife, and the messenger, Chase, who boarded at the Exchange; also Patterson, the saloon keeper, and all suspected parties. He was not to make himself known to Floyd, of the Exchange, or to McGibony, the local detective. I had also given Porter similar instructions. I suggested to him the propriety of lodging at some low boarding house where liquor was sold. He was to keep me fully posted by letter of the movements of all suspected parties, and if any of them left town to follow them and immediately inform me by telegraph who they were and where they were going, so that I could fill his place in Montgomery. Having given him his instructions, I selected for his disguise a German dress. This I readily procured from my extensive wardrobe, which I keep well supplied by frequent attendance at sales of old articles. When he had rigged himself up in his long German coat, his German cap with the peak behind, and a most approved pair of emigrant boots, he presented himself to me with his long German pipe in his mouth, and I must say I was much pleased with his disguise, in which his own mother would not have recognized him. He was as fine a specimen of a Dutchman as could be found.
