What motivates him? Why did he do this? Does he regret his actions? Three main questions for someone who committed a crime or tried to kill another person. The author of this book, Ben Cave, is a leading UK forensic psychiatrist. Its main task is to find out the motives of the person in custody and establish why the crime was committed. To work in this area you need strong nerves, a good stomach, an understanding of legal and psychiatric language, and also the ability to look into the abyss and not recoil when you see a real monster at its very depths. This book is about working in prisons and secure hospitals, diagnostics and treating people with mental disorders such as delusions, schizophrenia, drug addiction, personality disorders and severe depression. Dr. Cave cites many of his patients' stories to illustrate what actually happens behind the locked gates of institutions that house dangerous individuals such as rapists, pedophiles, drug addicts, child killers and those who want to commit suicide.
