An interesting read about Lady Elizabeth Foster, known historically as Bess and her attachment to the Fifth Duke (William) and Duchess (Georgiana) of Devonshire. The author did a good job filling in details from Bess's personal papers, never seen before outside of her family. I have to say right here, if you have seen the film The Duchess, or have read any of the back story about the love triangle she, William and Georgiana shared, this book deserves your attention if only because it does open Bess's character up in her own words and through the affectionate view her descendant's proffer. The jury is still out on whether or not Bess and Georgiana were ever lovers, they did however, enjoy a most passionate and extraordinary friendship. No one could've loved, saved or betrayed Georgiana as Bess did. In Georgiana's cold, complicated marriage to William, Bess was like the warmth of the sun on a frosty morning. Sadly, Bess had needs and desires of her own that her relationship with Georgiana couldn't fill. Chiefly, she needed William to help her eventually see her sons, which Her estranged husband refused to let her visit. Bess's ability to manoeuvre her way throughout the Devonshire's confidences, support and marriage are wholly unique amongst mistresses. She did this in the comfort of their homes, amongst their Kith and kin without prick of conscience. Nor did it faze her that Lady Spencer, Georgiana's mother despised her and wrote treatise after treatise imploring Georgiana to dispense with Bess. The Cavendish family didn't like or trust her either. She was bold as a fox in a hen house, she made herself necessary to them. Therefore, she became absolutely resolute and immovable from their lives, a true aristocratic-marital parasite. When William who made a serial career of producing children out of wedlock, even while being married to Georgiana, (he fathered a daughter before his marriage, who his young bride was forced to raise and two more with her best friend, Bess, who they smuggled into the household and raised along with his legitimate children by Georgiana), but when the longsuffering Georgiana found comfort in the arms of Earl Grey, and fell pregnant, he callously forced her to give the child up or she would forfeit her right to their children. This book is a good read. Depending on how much one has read of their history and your personal bias, would determine how you process this book. To my mind, I found it very pro Bess, nearly to the point of sainthood. I wondered why and came to find that the collaborator on this book, is Jane Dormer, the great-great-grandaughter of Bess's second child by William, Fifth Duke of Devonshire. So it stands to reason she would want some how clear up Bess's long-standing reputation as a double crosser and usurper of Georgiana's rightful place in her household/marriage. It's another perspective, one heretofore unseen. I recommend it because it is another piece of the puzzle. It was a fascinating, well researched book. It's plain to see the affection Bess's posterity hold her in and it must have been something they long wanted to "clear up" on her personal/historical account. Did it change my overall opinion of Bess Foster? No. But I cannot deny she made a way for herself in a time when most in her circumstances would have died in ruin and poverty. Her very life, health, comfort, and place in society was all due to the kindness of the Devonshires. Women had very little power back then. Their chances/choices were truly limited. She could have ended in a convent or worse. Not to mention being shunned by polite society. Bess had a grit and tenacity many lack. I don't say that's always a good thing, but her life and times are interesting. This is helpful in that it does aid one in trying to sketch out her character. She was in my opinion very adroit in her personal interactions and knew where "it" was at. She had her pulse on current events and had a variety of important devoted friends. This book has become a valuable addition to my personal library, one I shall dip into time and again.
