Merritt was graciously pleased to be agreeable. Moreover, he was utterly puzzled and absolutely consumed with an overpowering curiosity. It seemed also to him to be a sheer waste of providence to discard such an offer. And the plate at Littimer Castle was superb!
Meanwhile Chris and Bell walked down the street together. "He was puzzled over the Rembrandt," Chris said. "Seeing that he has our picture—"
"No doubt about it. The picture was rolled up and stood on the mantelshelf. I followed Merritt's gaze, knowing perfectly well that it would rest presently on the picture if it was in the room. At the same time, our interesting friend, in chuckling over the way he has deceived us, clean forgot the yellow pawnticket lying on the table."
"Dr. Bell, do you mean to say that—"
"That I know where your diamond star was pledged. Indeed I do. Merritt had probably just turned out his pockets as we entered. The pawnticket was on the table and related to a diamond aigrette pawned by one James Merritt—mark the simple cunning of the man—with Messrs. Rutter and Co., 117, High Street. That in itself is an exceedingly valuable discovery, and one we can afford to keep to ourselves for the present. At the same time I should very much like to know what Rutter and Co. are like. Let me go down to the shop and make some simple purchase."
Rutter and Co. proved to be a very high-class shop indeed, despite the fact that there was a pawnbroking branch of the business. The place was quite worthy of Bond Street, the stock was brilliant and substantial, the assistants quite above provincial class. As Bell was turning over some sleeve-links, Chris was examining a case of silver and gold cigarette-cases and the like. She picked up a cigar-case at length and asked the price. At the mention of fifty guineas she dropped the trifle with a little moue of surprise.
"It looks as if it had been used," she said.
"It is not absolutely new, madam," the assistant admitted, "therefore the price is low. But the gentleman who sold it to us proved that he had only had it for a few days. The doctor had ordered him not to smoke in future, and so—"
Chris turned away to something else. Bell completed his purchase, and together they left the shop. Once outside Chris gripped her companion's arm excitedly.
"Another great discovery," she said. "Did you see me looking at that cigar-case—a gun-metal one set with diamonds? You recollect that Ruth Gates purchased a case like that for that—that foolishness we thought of in connection with Mr. Steel. The case had a little arrow shaped scratch with the head of the arrow formed of the biggest diamond. Enid told me all this the night before I left Longdean Grange. Dr. Bell, I am absolutely certain that I have had in my hand just now the very case bought by Ruth from Lockhart's in Brighton!"
