“I certainly do,” was my reply, and then I told her of my journey to Italy, and of my discovery of her daughter with Moroni in Florence.

“But how did you know my daughter?” she asked.

“Because on that fatal night I saw her in a house in London.”

“You saw her! Where?”

“In the house of a mutual enemy.”
