Gluck: Her Biography by Diana Souhami:
The life of Gluck’s London in the thirties went on relatively undisturbed by the turbulence of international money markets, unemployment at home and German rearmament. She continued to produce ever more polished paintings and her 1937 exhibition was as successful as that of 1932. Two years later war swept away the world of high style she inhabited. She lost her home, her social circle, her sense of direction. She faded from the public eye and was never to regain her early fame. But more violent than war was the onslaught of love. It hit her in 1936 and gave her great pleasure and then great pain. She never really recovered from it.
