Query: Very well written, but the immorality spoils it

I have always liked Dorothy Gilman's Mrs Polifax novels. They are well-written spy stories with danger and suspense, but no graphic violence or immorality.In Caravan, Gilman writes a much more serious story of survival and hardship. Without giving the plot away, i will say that the story is riveting and well written. What kills the story is the sexual immorality she includes-not just mentioning it, but JUSTIFYING it! No matter what hardships we face, we MUST stay true to right values and live a decent life-this the main character (Charissa) failed to do.When she found out that her husband killed her lover, she contemplating killing him, but didn't. Good-it showed she has decency and a knowledge of right and wrong. But this evaluation was turned on its head when instead she enters an adulterous relationship for DECADES! It is really showing how sick society is when this is supposed to be the heroine of the story!
