Being together is not always the love-strewn path of true happiness rolling off into the sunset. It involves all sorts of other issues that come up to investigate that relationship with questions, pain and trouble. Perhaps infidelity is the most corrosive. The wronged partner seeks justice and answers as well as feeling betrayed and hurt. The other almost certainly knows their behaviour is wrong but seeks to justify it with barely literate utterances. The relationship may not survive, trust and respect will be damaged even broken. Our classic authors including Marjorie Bowen, Gustav Meyrink, Kenneth Grahame, Thomas Hardy and many others bring all facets of this genre into needle-sharp focus.
