"By the way, how is your good wife?"
"Very well; but allow me to finish. This other letter, without address, is for you."
"For me?"
"Yes; and you must give me your word of honor not to read it until half an hour after I have left you."
"Half an hour after you have left me?"
"Yes; will you promise?"
"If it will oblige you, I promise."
"Thanks; I rely upon your word."
"You may safely do so; I haven't thirty-six words in serious matters; but the other letter?"
"When you have read what I have written to you, you will see what I ask you to do; and I am confident that you will carry out my intentions."
