I read a lot of historical fiction, some of it good, much of it mediocre. This book, though, I loved unreservedly. Barrett tells this highly-plotted story of Victorian sexuality and hypocrisy in a 'knowing' way - the reader is well aware that the story is historical, but seen through 21st-century eyes.
The story begins with the births of two babies in the same house. The widowed Duchess of Fainhope is delivered of a baby boy who dies shortly after birth. On discovering the secret birth of a boy to the governess, Miss Mantilla, the Duchess arranges for the babies to be switched. The Duchess will bring up the governess's baby as her own, the existence of an heir (her two daughters don't count) ensuring she will be able to remain in her home, much to the displeasure of her brother-in-law Lord John.
Barrett's writing shimmers, her control absolutely assured. If at times the reader feels that character development is sacrificed to the manic twists and turns of the plot, nevertheless the book is adorably readable and engaging. Most of the main characters are fairly unpleasant, but they are such fun to read about that their likeability hardly matters.
Barrett wears her research lightly - at no point does the story get bogged down in 'history lesson' details. A fun, yet at times thought-provoking, romp.
