"Worth what?" asked Roland.

"Well, much more than twelve thousand."

"The only blue pearls in the world?" he said, puzzled.

"There's a lot about this necklace you don't know," I said smiling. "All in good time. Go on with your story."

"Well, that's all, isn't it?" said he. "At least you know the rest. Why these fellows were so careful of details, you will even find their imprint in gold inside the case. Jones and Sanford, such and such a number, Maiden Lane."

"Hm! I have a case on my hands now!" I said meditatively. "It may take me six months or more to clean this up."

"I'll work with you," he said.

"My dear fellow, I like you better every minute," I said, smiling at him. "But you'd make the worst detective in the world."

"Oh, well, maybe I would," he said.

"There's no need for you to await the outcome of the case," I said. "We have the evidence right in hand to clear you. I'll lay it before Miss Hamerton to-morrow morning."
