“It cost fifty dollars in Paris,” said Mrs. Hamilton.

“But you set a higher value upon it for other reasons?  Just so.”

“You are right.”

“Will you favor me with an exact description of the article?” said the detective, producing his notebook.

Mrs. Hamilton did so, and the detective made an entry.

“Have you ever had anything taken out of your house by outside parties?” he asked.

“On one occasion, when my brother was visiting me, his overcoat was taken from the hatstand in the hall.”

“A sneak thief, of course.  The glass, however, was not so exposed?”

“No; it was not on the lower floor at all.”

“It looks, then, as if it was taken by someone in the house.”

“It looks so,” said Mrs. Hamilton gravely.

“Have you confidence in your servants?  Or, rather, have you reason to suspect any of them?”

“I believe they are honest.  I don’t believe they would be tempted by such an article.”

“Not, perhaps, for their own use, but a glass like this may be pawned for a considerable sum.  Being of peculiar appearance, the thief would be hardly likely to use it himself or herself.  Detection would be too sure.”

“No doubt you are right.”

“How long has the glass been missing?” resumed the detective.

“Three days.”

“No doubt it has been pawned by this time.  Your course is clear.”

“And what is that?”

“To make a tour of the pawnshops, and ascertain whether such an article has been brought to any one of them.”

“Very well, Mr. Lynx.  I leave the matter in your hands.  I trust everything to your judgment.”

“Thank you.  I will try to deserve your confidence.  And now, good-day.  I may call upon you to-morrow.”

“Mr. Lynx left the presence of the lady, and went downstairs.  He had just reached the bottom of the staircase, when a thin lady glided from the rear of the hall, and spoke to him.

“Are you the detective summoned by Mrs. Hamilton?” she asked.

“Yes, madam,” answered Mr. Lynx, surveying housekeeper attentively.

“I am Mrs. Hill, the housekeper,” said she.  “I may add that I am a cousin of Mrs. Hamilton’s.”

Mr. Lynx bowed, and waited for further information.  He knew who was addressing him, for he had questioned Mrs. Hamilton as to the different inmates of the house.

“I stopped you,” said Mrs. Hill, “because I have my suspicions, and I thought I might help you in this investigation.”

“I shall feel indebted to you for any help you can afford.  Do you mind telling me upon what your suspicions rest?”

“I don’t like to accuse or throw suspicions on anyone,” said the housekeeper, but I think it is my duty to help my cousin in this matter.”

“Undoubtedly,” said Mr. Lynx, noticing that she paused.  “Proceed.”
