"But, surely, Jim Denton didn't send this box," said the detective. "If he's sweet on the girl he wouldn't want to poison her." "Well, hardly, Tyler," laughed another of the lunchers. "Perhaps he intended it for Mag," suggested another. "If he's tired of the girl he may be trying to fix her." "Pshaw! He doesn't have to resort to such measures as that! What could a poor girl do to injure Jim Denton? No, Tyler, you'll have to look somewhere else for your poisoner, I reckon," said one of the oldest men in the whole establishment. "Who gave you the box in the first place?" asked the detective of Sam. "I mean, who told you to give it to Miss Marvin?" Sam spoke up promptly, for he had nothing to hide. "A kid gave it to me at the door--a messenger boy--who said he was in a tearing hurry." "Did you sign for it?" asked the detective, looking sharply at the boy. "Naw, I didn't sign nothin'; he didn't have no ticket." "Then he wasn't a messenger at all," was the reply, "and you are a big dunce, Sam Watkins, that you didn't know it!" "Well, I thought it was straight, anyhow," whispered the boy. "How was I to guess that some one was tryin' to pisen Miss Marvin?" Ben Tyler took the box carefully and replaced the wrapper; then, telling Sam to follow, he went straight to Mr. Denton's office.

Mr. Denton cross-questioned him, but there was nothing further to learn. A boy had handed the box to Sam and told him to give it to Miss Faith Marvin. After Mr. Denton and the detective had examined the candy carefully they held a consultation as to what should be done about it. "We must have it analyzed at once," said Mr. Denton, anxiously. "That is the only way of proving the matter." The detective nodded. He knew that came first, but it needed no analysis to convince him that the candy was poisoned. "Has she ever received a similar box that you know of?" asked Mr. Denton. The detective hesitated for a moment. He hardly knew how to tell him. "I believe she has, sir," he said, after a minute; "but I would advise you to ask the young woman herself, for I can only repeat what may be idle gossip." "You are right," said Mr. Denton, touching an electric button and sending the boy who answered to the department for Miss Marvin. In less than five minutes Faith entered the office, but before he came the detective slipped a newspaper over the box of poisoned candy, and a nod of the head showed that Mr. Denton understood and approved of the movement. "Miss Marvin," said Mr. Denton, "I wish you to answer a question: Are you in the habit of receiving boxes of candy as presents?" With Mr. Gunning's remarks still burning in her brain, Faith could not help blushing at this unexpected question. She finally controlled herself and answered firmly:
