"Then, Sylvia, it's your turn."
"May I choose exactly what I want?" asked Sylvia.
"Certainly you may," replied Dr. Severn.
"Then I'd like to hear the story of that little carved ivory locket that's hanging on your watch-chain. It looks like a charm too."
A spasm of pain crossed the doctor's face at Sylvia's words, but he recovered himself in a moment.
"That would not interest you, dear child," he said gravely. "It is not a curiosity such as the other things I have shown you."
"It's a charm, though, isn't it?" asked Sylvia. "I've been noticing it all the afternoon. It's so exactly like another I've seen."
"That could hardly be," said Dr. Severn. "This carving has no duplicate."
"But I know one that's its own twin," persisted Sylvia. "It's the same size and shape, and has the same carving on it, these little three-cornered kind of leaves round the edge, and these marks like queer letters in the middle. I couldn't possibly forget it."
"Where did you see it?" enquired Linda.
