Betrayal Book

The play begins in the present, with the meeting of Emma and Jerry, whose adulterous affair of seven years ended two years earlier. Emma's marriage to Robert, Jerry's best friend, is now breaking up, and she needs someone to talk to. Their reminiscences reveal that Robert knew of their affair all along and, to Jerry's dismay, regarded it with total nonchalance. Thereafter, in a series of contiguous scenes, the play moves backward in time, from the end of the Emma-Jerry affair to its beginning, throwing into relief the little lies and oblique remarks that, in this time-reverse, reveal more than direct statements, or overt actions, ever could.
