'I first met Robert Allerton in prison, where he was captive and I was not... He was a powerful broad-shouldered Cockney [who] had spent his childhood in poverty and much of his manhood in prison; and he had a long record of violent crime.' Tony Parker, from his Introduction

Tony Parker's first book The Courage of His Convictions (1962), constructed out of his candid and illuminating dialogues with career criminal Robert Allerton (credited as co-author), is a stunning work that displays all the skills and virtues Parker would bring to his subsequent career as an 'oral historian' of the lives of society's marginal figures.

'This intimate autobiography is a revelation - it provides the first psychological insight into the mentality of that frightening, mysterious and pathetic product of our society, the professional criminal.' Arthur Koestler
