It was Winston Churchill who popularised the phrase Black Dog to describe the bouts of depression he experienced for much of his life. Johnstone, a sufferer himself, has written this moving and uplifting insight into what it is like to have a Black Dog as a companion and how he learned to tame it and bring it to heel.
