Contrary to their expectations, Mrs. l’Estrange was neither ill nor cast down. Perhaps she did not realize yet that her home had just been burned to the ground. At any rate, when Mr. Donahue carried her into the hotel, she rested her cheek on his shoulder and said softly:

“You find me a broken old woman, Ignatius.”

“No, no, Virginia. Only much paler and thinner. There is a great doctor who is an intimate friend of mine, and he has promised to come down in a few days and have a look at that spine of yours. I have enormous faith in him. I believe he can cure you.”
