Alice Oswald has won several literary awards.

    The book opens with Leaf Fielding's arrest in a pre-dawn police raid and ends five years later with his release from jail.The narrative moves back and forth between the harsh world of prison and his previous life - from a childhood at a brutal boarding school onto undergraduate days and his LSD epiphany in the summer of love, 1967.Acid transformed him in an instant from nerdy scholar to footloose freak. His ten years of adventures in the hippie underground gave the title to this book - a quote from a Bob Dylan song - they also took him across Europe, to the Andes, to Indochina and on to the edge of the known universe. They also led inexorably to his downfall.

    Jack Witney served twenty-five years in prison although he shot no one and was released on appeal, only to be murdered in his Bristol flat a few years later. John Duddy died in Parkhurst after fifteen years. But Harry Roberts, by his own admission the instigator of the crime and the most notorious, was released from prison after forty-eight years in 2015 making national front page news. What could possess an apparently rational and sane man, albeit an habitual criminal, to commit such a callous and ruthless act? What kind of a man is he? How can an ordinary person understand what he did? Should he be forgiven?50 years later, the full story for the first time.
