In Victorian times, the less said about human foibles . . . the better. "Gentlemen" were allowed to sow their oats as long as they did it discreetly while women were chattels of their husband's reputation in society. Naturally, one didn't mix with those of the lower classes.
Into that straight-laced environment, Anne Perry ingeniously introduces the taboos -- non-matrimonial sexual relations, love and lust among those of different social classes . . . and the consequences of sin.
As the book opens, a woman has been brutally murdered in an unusual way on upper-class Cater Street. Supercilious reactions follow, and the police are encouraged to stay away. When the murders continue, the self-satisfied lives begin to fray at the edges. Could the murderer be one's father . . . or brother?
Into this environment, two women find themselves with unexpected suitors from stations above and below them. Their wooings provide for fascinating reading.
The mystery side of this book will leave most reader dissatisfied. There is little of the police procedural or the "little grey cells" to entertain and amuse readers. Yet the mystery problem itself from the view of a hamstrung police force is quite challenging.
You will probably find yourself intrigued enough by this book to want to read more in the series . . . and you have a treat ahead of you as the rich characters expand and evolve.
