As Used On the Famous Nelson Mandela is a deeply funny, deeply disturbing account of Mark's rampage through the arms trade. Under a fairly flimsy disguise and with the use of some worryingly poor accents, Mark set off on a journey of discovery in the company of arms dealers, torture victims, politicians, cops, crusties and geeks. The result is a shockingly entertaining read.

Embedded within the sharpness of his humour is the truth of an industry fraught with loopholes, complacency and greed; that allows corrupt regimes to kill, maim and displace, but whose deals are often subsidised by the British taxpayer.
