Michael X aka Michael de Freitas, aka Abdul Malik is - as Williams' fascinating biography makes clear - a more complex figure than the simple monster of popular lore. (Which is not to say he didn't act in monstrous ways.)
Tracing his days as a Rachman-era Notting Hill hustler, to a 60s counter culture revolutionary, black power activist, and his ultimate descent into Manson-like madness in Trinidad, Williams skilfully captures the era and the man.
Though the book reads more like a piece of social history than a non-fiction novel (in the vein of In Cold Blood), it is a page-turner nonetheless. I finished it in two days of straight reading.
Arguments of Michael's innocence of the crimes which led to his ultimate downfall - which to his credit Williams doesn't entirely endorse but does rehearse - are less convincing, and there is a good argument that Williams could have drawn more rounded portraits of Michael X's victims.
But overall, this is a vital, fantastically-researched piece of work and will be a valuable historical resource in years to come.
