“Bob Wood, he was the one who insulted you, wasn't he?”

“Yes, father, but that was a long time ago,” said Mary. “Do let Quincy read the rest of it.”

“A brutal murder was committed last night at the Ellicott Mills,” Quincy continued. “The unfortunate victim was Mr. Samuel Ellicott, the treasurer and principal owner. He was found sitting at his desk with his head crushed in. The blood-stained implement of destruction has been discovered. Robert Wood, Jr., a native of the adjoining town of Fernborough, has been arrested and held without bail. Young Wood has been an employee at the mill, but had aspired to the hand of Mr. Ellicott's only daughter Mabel. Mr. Ellicott was firmly opposed to the match, and, with the view, probably, of forcing the young man to leave the city, had discharged him from his employ. Mr. Ellicott was busily engaged in making preparations for pay day, which occurs to-day, and was alone in his office at the time. There seems to be no doubt of the guilt of the accused. His cane was found in Mr. Ellicott's office and must have been used to inflict the murderous blows which have deprived Cottonton of one of its most enterprising and respected citizens.”

“What do you think of that, Mary?” asked Quincy.

“I don't know yet. What do you think, father?”

“The case has no mystery—no charm for the detective's mind. I was thinking that naughty boys who plague little girls often become wicked men. Now, what do you think?”

Mary did not answer at once. When she did speak it was the result of deliberation. In a small way she had often tried to help her father out in solving some of the mysteries that had come up in his line of work, and now the detective instinct in her was strongly aroused as Quincy knew it would be.

“Quincy and I both know the young man,—not pleasurably, I'll admit,” she said, finally. “Everybody thinks him guilty, but we have no right to join the multitude without cause. He may be innocent. It would be a double victory to repay an enemy with kindness, and, perhaps, save an innocent man's life.”

“Just what I thought you would say,” cried Quincy. “I feel too that there is a chance that Wood is not the one. But what can we do?” he continued.

“First, you must go and see Bob Wood's father, Quincy, and tell him that I am going to investigate the affair, with my father's help. But tell him he must be quiet about it. If we are to accomplish anything, it must be done without any one knowing we are interested in the matter. Father and I will look over all the papers that have reports of the trial, and, perhaps you had better attend the trial yourself, and make careful notes, for the papers do not always get things just straight. Then, I want to see Miss Mabel myself, and see what she says.”
