"I confess that something of the kind was in my mind," said Quarks excitedly, "but the missing books are going to help us. The old gentleman had not read these books himself. See, Wigan, uncut pages; at least"--he took out a penknife--"not uncut, but carefully gummed together. I hadn't thought of this."
He slit the pages apart, and from between them took a ten-pound note. Other pages, when unfastened, yielded other notes--five pounds, twenty pounds, and one was for fifty pounds.
"Enough, Wigan!" he exclaimed. "We've something better to do than find bank-notes. You must see the constable at once, and tell him there is treasure in this house which requires special protection. Then communicate with the Birmingham police, and tell them not to lose sight of Charles Eade, and let them also have a description of Mrs. Ashworth. I expect she is lying low in Birmingham."
"I don't follow your line of reasoning, professor."
"I had no very definite theory beyond thinking that Mr. Parrish must be a man of considerable means," said Quarles. "That fact once established, we had a motive for the murder, which did not seem applicable to Michael Hall. It was said that nothing beyond the salver was missing. Only Mrs. Ashworth could establish that fact. You remember Zena's question: 'How was it, since people were such early risers in Thornfield, that Mrs. Ashworth had to wait so long before anyone came?' There was one obvious answer. She was up much earlier than usual that morning, perhaps had not been to bed that night. The constable had said that the village was not awake. Again, it was Mrs. Ashworth who gave information about the nephew in Birmingham. It is possible Parrish may have mentioned him to his housekeeper, but, since she had only been with him a year, and the old gentleman held no communication with his nephew, it is unlikely. Once more, the housekeeper was a little too definite about the time. She had a story to tell. The precision might be the result of careful rehearsal. These points were in my mind from the first, but they were too slight for evidence. Now the missing volumes give us the link we want. Who could have taken them? Either Mrs. Ashworth, or someone with her connivance. I don't think it was Mrs. Ashworth. I believe it was the man who murdered Mr. Parrish."
