"Now, Mr. Reid went into the room and closed the door, carrying with him Mr. Curtis's knife," went on The Thinking Machine. "I can't tell you from _personal observation_ what ha...

"Then another telegram came from the Lincoln Club in Pittsburg. The name of Harry Pillsbury appeared as a visitor in the book in January, three years ago. It was you--Manning is...

"An odor of strong rose perfume," he said. Then: "Miss Clarke also told me that she had worked in a bank which had been robbed under circumstances identical with this by one Wil...
