“Pardon; mademoiselle is keen, but in this she is mistaken. Casimer is not the baron; he did fight for Poland, and his name is known and honored there. Of this I solemnly assure you.”

She stood up and looked him straight in the face. He met her eye to eye, and never wavered till her own fell.

She mused a few minutes, entirely forgetful of herself in her eagerness to solve the mystery.

Hoffman stood so near that her dress touched him, and the wind blew her scarf against his hand; and as she thought he watched her while his eyes kindled, his color rose, and once he opened his lips to speak, but she moved at the instant, and exclaimed,—

“I have it!”

“Now for it,” he muttered, as if preparing for some new surprise or attack.

“When uncle used to talk about the Polish revolution, there was, I remember a gallant young Pole who did something brave. The name just flashed on me, and it clears up my doubts. Stanislas Prakora—‘S. P.’—and Casimer is the man.”

Helen spoke with an eager, bright face, as if sure of the truth now; but, to her surprise, Hoffman laughed, a short, irrepressible laugh, full of hearty but brief merriment. He sobered in a breath, and with an entire change of countenance said, in an embarrassed tone,—

“Pardon my rudeness; mademoiselle’s acuteness threw me off my guard. I can say nothing till released from my promise; but mademoiselle may rest assured that Casimer Teblinski is as good and brave a man as Stanislas Prakora.”

Helen’s eyes sparkled, for in this reluctant reply she read confirmation of her suspicion, and thought that Amy would rejoice to learn that her lover was a hero.
