The one-act play opens with Devlin and Rebecca, described as "Both in their forties", talking in what appears to be a home living room on an early summer evening. As the play develops, it becomes clear that Devlin and Rebecca are probably married, although their relationship to each other is not defined explicitly; it must be inferred. Initially, Devlin seems Rebecca's husband or lover, her therapist, and potentially her murderer. Some critics have described their discussion as more between a therapist and his patient than between two lovers or between a husband and a wife.
