First of all this is a great story. The plot keeps you guessing until the very end.

This may not strike you as a promising source of interest but with the other layers of life revealed by the writer it provides a dramatic background.
Strong characters conflict in this period of repressed sexual and social habits. The senseless loss of life in the war (1914-18) of the young men of a generation and the effect on the lives of those who survived and on the lives of the women left needing to be loved is another element of the background.
