For me there was not enough flesh on the bones of this story to leave me with a strong image of what Harriet Cohen was really like, or for that matter her lovers/friends, nor of the way she and them lived their lives. There were too many quotes from letters, many of which were repetitive, and the story became somewhat tedious because of that I think.
The state of her health was also rather over-emphasised: she was at death's door and worsened (?) so many times it was rather hard to imagine how she obviously did survive whilst also managing (in the 1920s and 1930s) to travel throughout and give concerts in the UK, Europe, and America, receive treatments for her illness in Switzerland, on top of continuing various amorous liaisons!
There are some errors in the text, including a few references to a place of retreat called Glencolumcille in Scotland: I cannot find this in Scotland, but there is such a place in north-west Ireland near Donegal.
The story is interesting but I feel that in some aspects it could have been so much better: undoubtedly Harriet Cohen must have been an exceptionally attractive person in many ways who did a lot more than play a piano.
Harriet Cohen was a very accomplished piano player and it is a shame that her playing - with many recordings on 78rpm vinyls - has not been transferred to CD.
