Morton said to me, on making one of his reports, that she would often determine to give up morphine and liquor, and live more respectably. Then she would become excited from the craving for the drug, and would take a dose, which would soothe her, make her amiable, and give her energy enough to do anything; gradually she would become wild again, and would be almost unbearable, while the maddening effect lasted, especially if she took any liquor to add to her temper; finally, the influence would pass off, leaving her weak, despondent, and stupidly affectionate. I saw that she was not likely to confess anything to any one, and I therefore decided to bring the affair to a crisis without delay. CHAPTER V. _A moneyed young Texan becomes one of Mrs. Sanford's Lodgers.--The Bonds are seen, and their Numbers taken by the Detectives.--Mrs. Sanford Arrested.--Sudden and Shrewd Defense by the Prisoner.--She is found guilty of "Involuntary Manslaughter" and sentenced to the Illinois Penitentiary for five years.--Misdirected Philanthropy, and its Reward.--Mr. Pinkerton's Theory of the Manner in which Trafton was Murdered._ Having discussed my plan with my superintendent, Mr. F. Warner, I sent for one of my youngest men, named Thomas Barlow, and gave him explicit instructions as to the course which he was to pursue in connection with Mrs. Sanford. On the first day of February, therefore, a young fellow called at Mrs. Sanford's about five o'clock in the afternoon, and asked if she had any rooms to rent. She was very civil to him, and offered him the room at the head of the stairs, for three dollars a week. While she was showing him the rooms, she asked him a number of questions about himself; and as he was a smooth-faced, innocent-looking young man, he told her all about his affairs. He said that his name was Thomas Barlow, from Texas, where his father was a great cattle-raiser; he had brought several hundred head of cattle to the city, and had sold them at a high price; he intended staying in Chicago for a short time, and then he should go up the Red River of the North, in the early spring, to do some fur trading, as he believed there was a good deal of money to be made up there, by any one with sufficient capital; he intended to have a good time in Chicago first, however.
