Faith was still staring at him speechlessly, but with questioning eyes. She could not help feeling some curiosity about the details of the story.
"First, I had to find the boy that brought the candy to the store," went on the detective; "then I traced it step by step until I reached Mag Brady. Her brother is in a drug-store; it was through him she got the poison."
"And where is she now?" asked Faith, beginning to tremble.
"In jail, where she belongs!" was the heartless answer. "Mr. Denton and I went to court this morning and had her locked up for safe keeping."
"Oh, I didn't think he would do it!" said Faith, almost ready to cry. "It is cruel, Mr. Tyler! Oh, I am so sorry for Miss Brady!"
"Well, I wouldn't be sorry for a person who tried to kill me," said the detective, sneeringly; "but, then, I'm no saint like you, Miss Marvin."
Faith looked at him quickly and could see a sneer on his face. It was plain that he had no special respect for saintliness.
When she reached her department she found every one talking excitedly, and, of course, Miss Brady's arrest was the topic of conversation.
"Here she comes!—here comes Mag's rival!" cried Miss Jones, when she saw Faith coming.
The "head of stock" had got down before her and was beginning to arrange her goods upon the counter.
