Mary became so interested in the case that she decided not to go to the White Mountains for the summer, and Quincy also remained in Fernborough, helping Mary as much as he could. Often they would go off on long tramps in the surrounding country, and once Quincy went to Boston and was gone several days. That they procured some evidence was clear from the satisfied remarks made by Mr. Dana, who approved of the lines on which they were working. Although they had made some headway they were not ready to present their theories when the time came for Bob Wood's trial. Many thought him innocent, but the jury were of a different opinion, and brought in a verdict of murder in the first degree. The day after the close of the trial, the district attorney of Normouth County was sitting in his office opposite the Court House. He was preparing his address opposing the granting of a new trial, which he knew would be proposed the next day by the counsel for the defence. He had gone over the evidence time and time again. He was a conscientious man. He felt that the law of the State had been defied--had been outraged--and yet within his heart was that natural feeling of sympathy and pity for the unfortunate being for whom but a few short weeks of life remained, and he could not help regretting the part he had been obliged to take in convicting the young man. At that moment, a clerk entered and said that a young lady wished to see him. In obedience to the direction given, the clerk withdrew; the door was opened again, and a blue eyed, fair-haired girl entered. Standing near the district attorney's desk, she said: “Mr. Harlow, as there is no one here to introduce me, I will introduce myself. My name is Mary Dana. My father is, or rather was, a detective for seventeen years in Boston, but our present abiding place is the town of Fernborough. In the city he often used to tell me of the cases on which he was working, and I would try to solve them with him. Robert Wood lived in Fernborough, and from the day of his arrest I have been much interested in the case, and with the help of my father and a friend of mine, Quincy Adams Sawyer, the son of the former governor, I have been trying to find the man who murdered Mr. Ellicott,--for I have never believed that Robert Wood was the guilty person.” She smiled, and added, “Detectives, I believe, are more often interested in strengthening evidence, and bringing about imprisonment and executions than they are in trying to prove people innocent.” “But, my dear young lady,” said the district attorney, “the young man whom you speak of has already been proved guilty by a fair-minded jury. There seems to be no question of his being innocent, and, after the jury have returned their verdict it is rather late to still try to prove him not guilty.” “What I have to tell you I think is important. Can't you spare me a little time?”
