The central situation of 'Tis Pity She's a Whore is an incestuous love between brother and sister, and it is hardly surprising that critics have differed widely in their interpretation of the exact meaning and significance of the play...All the love affairs in the play end in disaster ...it would even be possible to read the play as a series of warnings against the destructive effects of passion."-from the introduction by N. W. Bawcutt
