The author herself sums up this biography in the introduction, and incredibly accurately. I tried to paraphrase it but can not write it better than the author (unsurprisingly ...) , so I will reproduce the summary here for those interested:
"There are many things that this book could or would not be. It would not be a book about lesbianism - Joe Carstairs was too singular and strange to be representative of anything other than herself. It would not be a tribute to feminist strength and success - after all, the principle by which she defined herself was male. It would not be a comprehensive or strictly chronological account - there are too many gaps in the available material. But it could be a book which connected Joe Carstairs to the century she spanned, a twentieth-century fable with a twist. And it could be a book which sought to find the stories which fastened together the scenes of her life."
If this summary appeals to you, I urge you to try the biography, it's just as described there. It tells the story of a fascinating woman, in a fascinating era who had the money, the will and the imagination to live a fascinating life.
I was glad of the reprinted photographs and sketches, there are 16 sides of black and white images on glossy paper and 24 on the same paper which the text is printed on. The pictures include reproductions of press clippings, also.
My small criticism is that I'd have loved to read the original obituary, written by Kate Summerscale, which prompted her to write the book. Reprinting it in the biography would have completed it - especially as it's the very first thing described in the introduction, I did expect to find it reprinted at the end. Thanks for reading through my thoughts and the summary, I hope you found them helpful.
