At that moment David Rossi appeared at the back, and the Princess welcomed him effusively.

"So glad! So honoured! Gi-gi, let me introduce you—Honourable Rossi, Don Camillo Luigi Murelli."

"Never been here before, Mr. Rossi? Then you must allow me to explain everything. Take this chair between Roma and myself. No, you must not sit back. You can't mind observation—so used to it, you know."

"And the upper circles?" asked Rossi.

"Oh," in a tired voice, "professional people, I think—Collegio Romano and University of Rome, you know."

"And the gallery?"
