Ruth Leon was married to theatre critic and journalist, Sheridan Morley. He'd suffered bouts of depression all his life, but after a mild stroke all his usual treatments failed and he descended into an unrecognisable person. Leon, herself a freelance journalist, was eventually faced with agreeing to a treatment not performed in the UK before, which would allow doctors to adjust his moods through an electronic implant. This is a heart-rending memoir of their relationship, the devastating effects of his illness, and explores what it means to be human in the face of suffering and experimental medical treatments.
