She opened her notebook at the page upon which she had written the guests’ names, and counted them. Fourteen people besides herself, and of that number she had met only five. Rather a slow beginning!

“If I only had Jane here, she’d know everybody in the place by now,” she thought wistfully. “Jane is clever, but she does jump at conclusions. Maybe I’m better off alone.”

She glanced at the notebook again and resolved not to bother yet with the names of people she hadn’t met. She’d concentrate instead upon the five that she did know. She began at the beginning with the girl with whom she had danced and eaten supper.

“Pauline Brooks couldn’t be guilty,” she decided. “Because she came to Stoddard House only a few days ago for the first time. After the first two robberies had taken place. So she’s out....

“Now I’m not so sure about Miss Henrietta Stoddard. She might even believe she had a right to steal things, because she was cheated out of her inheritance. Yes—I’ll watch Miss Stoddard carefully.

“Next those two Weinberger women. Hardly possible, when the mother lost her own watch. Of course, thieves sometimes pretend to have things stolen, just to establish their innocence, the same way murderers often wound themselves—for alibis. But, just the same, I believe those women are honest. They’re pretty well off, too, to judge from their clothes and their jewelry.”

She came to the last person she had met—the old lady who had come to the book-club meeting with a cane—Mrs. Moyer. Mary Louise’s face broke into a smile. Nobody in her right senses could suspect a person like that!

That was all. Except the secretary, Miss Horton, whom she had met at the desk.

Mary Louise closed the notebook and put it on the table beside her. That was enough for tonight; now she’d try to get some sleep. She put out the light and opened the window. Snow still covered everything except the streets and the sidewalks, and the moon shone over the roofs of the buildings beyond. Right below her side window was a fire escape, which made her feel somehow safe and secure.

It was not nearly so quiet here as in Riverside; automobile horns honked now and again, and the sound of trolleys from the street in front was plainly heard. But Mary Louise was not worried about the noise, and a few minutes after she was in bed she was sound asleep.
