Pimpernel and Rosemary by Emma Orczy

Rosemary went slowly up the veranda steps. She did not feel that it would be loyal to pry into Elza's secrets, but at the same time she wanted to remain well within call. From where she was she could see Peter's broad shoulders blocking the French window which gave on the drawing-room. From somewhere in the house, both above and below stairs, came the sound of laughter and song.

A moment or two later she heard Elza's footsteps behind her on the gravel walk, and presently Elza was there, going up the veranda steps beside Rosemary. She did not say a word, and Rosemary asked no questions. She could see that Elza was preoccupied. She also noticed that the letter-or whatever it was-was not in Elza's hands.
