Whosoever Shall Offend by F. Marion Crawford

With a single movement Regina was on her feet, for she had been taken by surprise, and her first instinct was to be ready for some new and unsuspected danger. In a flash it seemed to her that since Corbario was in the house, he might very possibly enter suddenly and take Settimia's defence. Regina was not afraid of him, but she was only a woman after all, and Corbario was not a man to stop at trifles. He was very likely armed, and would perhaps shoot her, in order to make good his escape with Settimia, unless, as was quite probable, he killed his old accomplice too, before leaving the room.

Regina stood still a moment, reflecting on the dangerous situation. It certainly would not be safe to release Settimia yet; for if Corbario were really in the house, the two together could easily overpower one woman, though she was strong.
