"Is that the dog that goes to the Deputy's apartment?"

"Certainly it is! His name is Black. I'll hold him while you open the door, Felice. There! Good dog! Good Black! Oh, the brute, he has broken away from me."

"Black! Black! Black!"

"No use, Felice. He'll he half way through the streets by this time."

"Dearest,—Been away from Rome for a few days, and hence the delay in answering your charming message. Don't trouble a moment about the dead-and-buried nightmare. If the story is true, so much the better. R. R. is dead, thank God, and her unhappy wraith will haunt your path no more.

"Still no news from London, but though I pretend neither to knowledge nor foreknowledge, I am still satisfied that we are on the right track.

"Dinner-party to-night, dearest, and I shall be obliged to you if I may borrow Felice.

I can deny you nothing, you see, but I am cruelly out of luck that my dark house must lack the light of all drawing-rooms, the sunshine of all Rome!

"How clever of you to throw dust in the eyes of your aunt herself! And these red-hot prophets in petticoats, how startled they will soon be! Adieu!
