Like many criminals, the Krays have always been a fascinating duo to both the British public and a more general worldwide audience since they give the average person a look into the criminal underworld of yesterday. Made more iconic thanks to the recent film starring Tom Hardy as both brothers, this book looks to be saying something different about the twins and adding to the knowledge that is already out there. The provocative title of the book suggests that the author was part of this criminal underworld, and therefore has insider knowledge and personal accounts to add to the subject area. As a result this would be a wonderful, and unique, addition to the shelf of anyone interested in true crime.
