HEADLEY'S DEBUT is more interesting for its portrayal of London's Jamaican immigrant criminal subculture than it's straightforward tale of the rise and fall of one hood. Basically if you've seen Scarface, you'll know the story. Headley's authentic vision of the milieu, with vivid descriptions of the role of music and food in the immigrant community, is what makes it worth reading. The thick Jamaican patois gets a little hard to follow at times, but it's no harder than Trainspotting, once you get used to it. Other than the descriptive element, the writing and plotting is extremely elementary.
