"Then, too," she added, "Miss Fulton's father is due on the nine o'clock train. Mr. Withers may stop down town to meet him."

"I'd forgotten about that," said Bristow. "We'll have to ask your help." He handed her the fragment of chain. "Will you be so kind as to take that back to Miss Fulton and ask her whether she recognizes it, whether she can identify it?"

Miss Kelly complied with the request at once.

She returned in a few moments.

"Miss Fulton," she reported, handing the links back to Bristow, "says this is a part of the chain Mrs. Withers wore round her neck night before last. She wore a lavalliere; it had two emeralds and eighteen rather small diamonds."

"Good!" exclaimed Greenleaf, glancing at the lame man. "I guess that fixes Perry."

"Undoubtedly," Bristow assented; and spoke to Miss Kelly: "I beg your pardon, but is Miss Fulton up this morning, or will she be up later?"

"She's dressing now. She wants to be up to meet her father."

"In that case, I'll wait until later. What I would like to have is a complete, detailed description of all of Mrs. Withers' jewelry. I wish you'd mention that to her, will you?"

Greenleaf was anxious to return to his office.
