" I suddenly recalled that it was here in the squalor and gloom of this sunken street, terrorized perhaps by a premonition of the future, that Mona clung to me and with a quivering voice begged me to promise that I would never leave her, never, no matter what happened. And, only a few days later, I stood on the platform of the Gare St. Lazare and I watched the train pull out, the train that was bearing her away; she was leaning out of the window, just as she had leaned out of the window when I left her in New York, and there was that same, sad, inscrutable smile on her face, that last-minute look which is intended to convey so much, but which is only a mask that is twisted by a vacant smile.
