This book concerns itself largely with the creation, as it puts it, of the Kray legend. Various events in their lives are retold, perhaps most interestingly the boyhood infection of diphtheria that the twins suffered, Ronald Kray especially severely, and the effect this may have had upon his mental state; possibly contributing to his paranoid schizophrenia. Their lives in the East End of Bethnal Green, their move to the 'West' with the establishment of the club 'Esmeralda's Barn' in Knightsbridge and their place within the swinging 60s are described. The factors that allowed the Krays unfettered activity for some time as Scotland Yard were warned off and the political influences that brought this about are discussed, particularly the role of their acquaintance with Lord Boothby. Perhaps, of necessity, much detail is omitted relating to their activities, e.g. the establishment of the 'Kentucky Club' and the range of their influence in the East End given that they had rivals. There are a few factual errors related to East End history, e.g. the abode of Anthony Armstrong-Jones was not Narrow Street, nor was David Bailey born or brought up in Bermondsey; this is a little disconcerting and points to a careless approach to research. Written in a journalistic style the book is neither great nor definitive but is interesting.
