This was either very subtle and went over my head, or it was very vague. The protagonist, who had been acquitted on the charges of her husband's murder, seemingly may or may not have been truly innocent. There was an implied moral dilemma involved because the husband had been crippled and suffering, and his death may have been merciful. Or maybe that wasn't the intended implication - I wasn't sure. Does it matter? The plot such as it is revolves around the acquitted woman's social life after she returns from her trial to her regular society life as a widow.
Although I like drawing room melodramas, this seemed to lack both substance and style.
