All the train-hands were immediately questioned, but none of their stories was in any way significant, except that of Newton Watt, the man in charge of the second car. He said that while busy counting over his way-bills and receipts he had been startled by the crash of broken glass in the ventilator overhead, and that at the same moment a heavily built man, wearing a black mask, had entered the car and said, "If you move, the man up there will bore you." Looking up, Watt said further, he saw a hand thrust through the broken glass and holding a revolver. Thus intimidated, he made no attempt to give an alarm, and the masked man presently left him under guard of the pistol overhead, which covered him until shortly before the train reached Morris, when it was withdrawn. He was able to locate the place where the crime must have been committed, as he remembered that the engine was whistling for Minooka when the stranger entered the car. This left about thirty minutes for the murder, robbery, and escape. Returning to Chicago, Mr. Pinkerton investigated the character of the man Watt, and found that he had a clean record, was regarded as a trusty and efficient man, and had three brothers who had been railroad men for years and had always given perfect satisfaction. Watt's good reputation and straightforward manner were strong points in his favor, and yet there was something questionable in his story of the mysterious hand. For one thing, no footprints were found in the snow on the top of the car. Brakeman Schwartz, the only man on the train who had not yet been questioned, "deadheaded" his way, in railway parlance, back from Davenport the following night on conductor Danforth's train, and reported to Mr. Pinkerton the next morning. He was a tall, fine-looking young fellow, about twenty-seven, with thin lips and a face that showed determination. He was rather dapper in dress, and kept on his gloves during the conversation. Mr. Pinkerton received him pleasantly, and, after they had been smoking and chatting for an hour or so, he suggested to Schwartz that he would be more comfortable with his gloves off. Schwartz accordingly removed them, and revealed red marks on the backs of his hands, such as might have been made by finger-nails digging into them. "How did you hurt your hands, Schwartz?" asked Mr. Pinkerton. "Oh, I did that handling baggage night before last," explained Schwartz; and then he related incidentally that as he was on his way back to Chicago, the conductor of the train, conductor Danforth, had discovered a valise left by somebody in one of the toilet-rooms. Later in the day Mr. Pinkerton summoned the conductor, who said that the valise was an old one, of no value; and, having no contents, he had thrown it out on an ash-pile. The only thing he had found in the valise was a piece of paper that attracted his attention because it was marked with red lines.
