congratulations. As for the girl, it was with difficulty she restrained her tears. "I think that we have witnessed a tragedy," said Bruce's acquaintance as they walked off; and the barrister agreed with him. He was sorry for Mensmore and his pretty supporter. Mayhap the loss of the match meant a great deal to both of them. That night he learned by chance that Mensmore lived at the Hotel du Cercle.

"And now, monsieur," cried the clerk, "we shall see what we shall see." The missive was addressed to the mysterious Sydney H. Corbett and had been forwarded by the Sloane Square Post-Office.
