Without attempting to answer those questions decisively, I may at least record that I never saw my mother and my sister together in Pesca’s society, without finding my mother much the younger woman of the two. On this occasion, for example, while the old lady was laughing heartily over the boyish manner in which we tumbled into the parlour, Sarah was perturbedly picking up the broken pieces of a teacup, which the Professor had knocked off the table in his precipitate advance to meet me at the door.

“I don’t know what would have happened, Walter,” said my mother, “if you had delayed much longer. Pesca has been half mad with impatience, and I have been half mad with curiosity. The Professor has brought some wonderful news with him, in which he says you are concerned; and he has cruelly refused to give us the smallest hint of it till his friend Walter appeared.”

“Very provoking: it spoils the Set,” murmured Sarah to herself, mournfully absorbed over the ruins of the broken cup.
