“Have you looked among her things yet?” asked the detective.

“No, because the conviction only came to me after she returned. I did have suspicions, I will admit, but I put them aside. When she came back I saw that she was uneasy and anxious, and only a few moments ago she asked to be sent home.”

“H-m,” mused the detective. “Suppose,” he continued, “that you call her down and let me talk to her as if I needed her assistance, she being the only member of the party available.”

The advice was acted upon, and presently Fannie, still with the handkerchief swathing her forehead, looking very nervous and pale, entered the room.

“Miss Alta,” began the widow kindly, “I am sorry to have disturbed you when you were ill, but we are in great trouble and we thought perhaps you might help us. Did you know that last night I lost my beautiful pearl necklace, the most precious thing I have in the world?”

Fannie showed great surprise.

“Did it not come unclasped and slip?” she suggested.

“I have reason to believe that it did not slip from my neck, because we have searched the place thoroughly. It must have been taken. I talked it all over with the other girls last night and they helped me look for it, but now I need some one else, and in their absence I have sent for you. Mr. Bangs, who is a detective, has come down to lend me his aid, and we thought we might take you into the conspiracy with us.”

The widow paused for breath.

Fannie sat down and folded her hands nervously.
