"You are looking at my new pamphlet, Pettifer, _The Prison Walls must Cast no Shadow_. I am hoping that it will have a great influence." "No," replied Pettifer. "I wasn't. I was looking at this," and he held up the little book. "Oh, that?" said Hazlewood, turning away with disappointment. "Yes, that," said Pettifer with a strange and thoughtful look at his brother-in-law. "And I am not sure," he added slowly, "that in a short time you will not find it the more important publication of the two." He laid the book down and in his turn he moved away towards the billiard-table. Margaret Pettifer remained. She had been struck by the curious deliberate words her husband had used. Was this the hint for which she was looking out? She took up the little book. It was a copy of _Notes and Queries_. She opened it. It was a small periodical magazine made up of printed questions which contributors sent in search of information and answers to those questions from the pens of other contributors. Mrs. Pettifer glanced through the leaves, hoping to light upon the page which her husband had been studying. But he had closed the book when he laid it down and she found nothing to justify his remark. Yet he had not spoken without intention. Of that she was convinced, and her conviction was strengthened the next moment, for as she turned again towards the drawing-room Robert Pettifer looked once sharply towards her and as sharply away. Mrs. Pettifer understood that glance. He was wondering whether she had noticed what in that magazine had interested him. But she did not pursue him with questions. She merely made up her mind to examine the copy of _Notes and Queries_ at a time when she could bring more leisure to the task.
