It would be impossible to describe the expression of astonishment on Edna Thurlow’s pretty face upon hearing these disclosures, but before she could collect herself and reply a stately, very handsome, and distinguished-looking woman entered from the hall, saying quite graciously:
“What was that I heard? Mr. Paulding acting under your instructions, sir?”
Carter turned and bowed, while Edna immediately introduced her mother, hastily informing her of the detective’s identity and his startling statements. The detective then accepted an invitation to accompany them to the library, where he not only dispelled their perplexity, but also greatly relieved their anxiety by telling them of his relations with Paulding and, in a strictly confidential way, the nature of his mission.
“As a matter of fact, however, I have called to see you on other business, Mrs. Thurlow,” he said a little later. “It is your intention, I have heard, to attend the reception ball of the National Guards to-morrow evening.”
“Yes, indeed, both of us,” Mrs. Thurlow replied. “I am one of the sponsors and the director of the ladies’ reception committee.”
“Is it to be quite an elaborate affair?”
“Yes, Mr. Carter, quite so.”
“I understand that you own a very valuable rope of pearls, which you intend wearing.”
“Yes, surely.” Mrs. Thurlow regarded him with a look of surprise. “When would I wear it, if not on such an occasion? I wonder at your having heard of my pearls, however.”
“I have heard something more,” Carter informed her. “I cannot honorably conceal the fact from you, property of such value being in jeopardy, but I hope you will consent to act upon my advice and instructions.”
