Despite an Italian background, J. P. Sperati lives in Essex where he has always been interested in television and film. To be precise it is the technical side of the art of film making, and in particular how different locations are used and seamlessly meshed together to make a coherent end product that fascinates. Hence his acclaimed series of location guides covering film series such as James Bond and Harry Potter. More recently he has turned his attention to two of his other passions, history and crime, and produced the first three in a series of In the Footsteps of … guides which deal with the likes of Jack the Ripper and the Kray Twins along with other more obscure criminals from the past.
