“A shabby trick,” said the Duke.

“Shabby?” said Guerchard in a tone of utter wonder. “How can anything be shabby in the case of a rogue like this?”

“Perhaps not—perhaps not—still—” said the Duke, and stopped.

The expression of wonder faded from Guerchard’s face, and he went on, “Well, Holmlock Shears recovered the Blue Diamond, and Ganimard nabbed Lupin. He held him for ten minutes, then Lupin escaped.”

“What became of the fair-haired lady?” said the Duke.

“I don’t know. I have heard that she is dead,” said Guerchard. “Now I come to think of it, I heard quite definitely that she died.”

“It must be awful for a woman to love a man like Lupin—the constant, wearing anxiety,” said the Duke thoughtfully.

“I dare say. Yet he can have his pick of sweethearts. I’ve been offered thousands of francs by women—women of your Grace’s world and wealthy Viennese—to make them acquainted with Lupin,” said Guerchard.

“You don’t surprise me,” said the Duke with his ironic smile. “Women never do stop to think—where one of their heroes is concerned. And did you do it?”

“How could I? If I only could! If I could find Lupin entangled with a woman like Ganimard did—well—” said Guerchard between his teeth.
