"I let the man keep it," Chris went on, more slowly, "with an eye to the future. The man had stolen the thing and I was in a position to prove it. He would be pretty sure to pawn the star—he probably has done so by this time, and therefore we have him in our power. We have only to discover where the diamonds have been 'planted'—is that the correct expression?—I can swear an information, and the police will subsequently search the fellow's lodgings. When the search is made the missing Rembrandt will be found there. Mr. Merritt would hardly dare to pawn that."

"Even if he knew its real value, which I doubt," Bell said, thoughtfully. "Henson would not tell his tool too much. Let me congratulate you upon your idea, Miss Chris. That diamond star of yours is a powerful factor in our hands, and you always have the consciousness of knowing that you can get it back again. Now, what are we going to do next?"

"Going to call upon Mr. Merritt, of course," Chris said, promptly. "You forget that I have his address. I am deeply interested in the welfare of the criminal classes, and you are also an enthusiast. I've looked up the names of one or two people in the directory who go in for that kind of thing, and I'm going to get up a bazaar at Littimer Castle for the benefit of the predatory classes who have turned over a new leaf. I am particularly anxious for Mr. Merritt to give us an address. Don't you think that will do?"

"I should think it would do very well indeed," Bell said.

The quaint and somewhat exclusive town of Moreton Wells was reached in due course and the street where the Rev. James Merritt resided located at length. It was a modest two-storeyed tenement, and the occupier of the rooms was at home. Chris pushed her way gaily in, followed by Bell, before the occupant could lay down the foul clay pipe he was smoking and button the unaccustomed stiff white collar round his throat. Merritt whipped a tumbler under the table with amazing celerity, but no cunning of his could remove the smell of gin that hung pungently on the murky atmosphere.

Merritt dodged his head back defiantly as if half expecting a blow. His eyes were strained a little anxiously over Bell's shoulder as if fearful of a shadow. Bell had seen the type before—Merritt was unconsciously looking for the police.

"I am so glad to find you at home," Chris said, sweetly.

Merritt muttered something that hardly sounded complimentary. It was quite evident that he was far from returning the compliment. He had recognised Bell, and was wondering fearfully if the latter was as sure of his identity. Bell's face betrayed nothing. All the same he was following Merritt's uneasy eye till it rested on a roll of dirty paper on the mantelshelf. That roll of paper was the missing Rembrandt, and he knew it.

"Won't you offer me a chair?" Chris asked, in the sweetest possible manner.

Merritt sulkily emptied a chair of a pile of cheap sporting papers, and demanded none too politely what business the lady had with him. Chris proceeded to explain at considerable length. As Merritt listened his eyes gleamed and a broadening grin spread over his face. He had done a great deal of that kind of thing, he admitted. Since Henson had taken him up the police had not been anything like so inquisitive, and his present pose was fruitful of large predatory gains. The latter fact Merritt kept to himself. On the whole the prospect appealed to his imagination. Henson wouldn't like it, but, then, Henson was not in a position to say too much.
