The play describes a trollop with a vivid imagination. With an aristocratic background borrowed from novels she’s read, she picks up a lonely man who has come down to London for a frolic, and takes him off to her basement apartment. His pretension to worldliness quickly goes sour, for he has no experience with women and is totally gauche in this new situation. Neither of them are really what they seem. One by one they trip away the pretences that mask their loneliness.
