One Wonders, What Fell off the Balcony?

This photograph (I thought it was a painting at first) has always piqued by interest: What is she looking at?

I like to concoct a Sensational plot from this image, where the maid has been terrorized by her master, a Count Fosco-like character (One recommends The Woman in White) and in a passionate moment, he tumbles backwards off the terrace to his death.  The maid watches his descent with mild curiosity, neither horrified nor particularly pleased.  She will go back into the house and continue to polish the Louis Majorelle Armoire.
