The Layer Cake is a hard bitten crime novel of 90’s underworld London that the movie was based on. However the book is worth reading because the plot is similar but different to the film.
I won’t go into too much depth because that would spoil it for you, but suffice to say its a great read. The book doesn’t have the slick quality of the film, primarily because it has more depth.
From the thought that has gone into it, one may wonder as to how J.J. Connolly got his knowledge. Having worked and lived in clubland during the late 1980s and early 1990s the type of characters Connolly describes brought me right back to my early and mid twenties.
