The crowd on the porch and in the street began to disperse slowly after the chief had told them none of them could be admitted. In small groups, they made their way to porches or into houses where they lingered, speculating, wondering, advancing impossible theories.

Why had death singled her out? Who would ever have suspected that there had been in her life any foothold for tragedy? The secrecy with which she had been struck down, the ease of the murderer's coming and going safely, roused their resentment. They sympathized with themselves as well as with the dead woman.

Confusedly, but at the same time with striking unanimity, they felt that this was not merely a mystery, but a mystery made ugly and shocking by base motives and despicable agents. In common with all mankind, they resented mystery. It emphasized their own dependence on chance. They began to guess at the best method for capturing the guilty.

The chief of police and the lame man had reached the porch of No. 9. There Bristow picked up from a table a scrapbook and a bundle of newspaper clippings. Following him into the living room, Greenleaf brought a paste pot and a pair of shears which the other evidently had been using in placing the clippings in the big book. He put them down on a table in one corner near Bristow's typewriter.

"Still figuring 'em out, I see," he said grimly.

He referred to Bristow's habit of reading murder mysteries in the newspapers and working them out to satisfactory solutions. That was Bristow's way of amusing himself while set down in Furmville for the long struggle to overcome the tuberculosis with which he was afflicted. In fact, as a result of this recreation, he had become known to Greenleaf, who had visited him several times.

He had rendered the captain considerable assistance in a minor case shortly after his arrival in the town, and Greenleaf was really amazed by the correctness of the lame man's solutions of most of the murder cases chronicled. He knew that Bristow had been right on an average of nine times out of ten, often clearing up the affairs on paper many days or even weeks ahead of the authorities in various parts of the country.

Bristow had his records in his scrapbooks to prove his contentions. Under each clipping descriptive of a baffling murder he had written a brief outline of his solving of the case and dated it, following this with the date of the correct or incorrect solutions by the authorities.

"But now," the chief added, as they sat down before the open fire, which earlier had fought against the chill of the cool May morning, "you can work one out right on the ground. And I'll be mighty glad to have your help—if you will help."

"Of course," said Bristow. "I'll be more than glad to make any suggestions I can."
