Saul and Alex. As teenagers, one brother went mad and the other stayed sane. What made the difference? Was Saul’s psychosis genetically driven, or formed by events in his childhood?

Aged 30, Saul changed his name in a symbolic attempt to make a break with 15 years of acute manic depression. It did not work. Five years later, now called Archie, he and Alex began to explore the psychiatric world together, across the fields of cognitivism, psychoanalysis and neuroscience. These are accounts of psychiatric dilemmas, or tales of the psychologically unexpected, told from a starting place of brotherhood.
