This book has been on a bookshelf in my home since 1997 but somehow I have never read it, to my chagrin. Atwood’s writing is impeccable, adopting the style of the mid-1800s in letters, for example. Her portrait of the enigmatic Grace Marks is breathtaking: poverty in childhood, a hard life in service, accused of being an accessory to murder at age 16 followed by 20 years of incarceration. The context of early versions of psychiatry and hypnotherapy are detailed carefully. Overall, a joy to read.
