Saunders dug into his pocket and pulled out a postal card. "This will tell you—or the photograph on it will."

The picture was a foreign one, bearing the strange characters of a Slavic language, such a card as is sold in every country with portraits of reigning or distinguished personages. The facsimile signature, in a bold feminine hand across the lower part of the picture, was "Carlotta."

"Do you believe me now, Griffin?" asked Saunders, with some sympathy showing on his face, which fact alone saved Mark from smashing it.

"I am afraid I must, Saunders. You had better tell me the whole of this."

"I will; for, as I have sized up the situation, it is best that I should. The Duchess ran away. She was supposed to be at San Sebastian with a trusted attendant. The attendant was evidently not to be trusted, for she disappeared, too. They were traced to London, then to Madeira, then to a North German Lloyd liner which stopped at the island on its way to America. Then to Boston. Then to Sihasset."

"This attendant you spoke of—what was she like?"

Saunders gave the description: "Dark, fairly stout, white hair, bad English, piercing black eyes, sixty years old, upper lip showing a growth of hair, slight wart on the right side of the nose."

"Madam Neuville!"

"So she's here with her, is she? I suspected that, but I have never seen the old lady."

"She doesn't go out much."
