This, the third book about veteran journalist, Mike Noble, and his photographer assistant, Liz McKendrick, is about the dangerous world of diamond smuggling. On holiday in Palma, Mallorca, they hear about the death, at Gatwick Airport in England, of a holiday rep and they are soon involved in following the trail of uncut diamonds, from the river beds of Angola, through North Africa to the island of Mallorca itself.Anna Charles' research for this book took her into the realms of so-called Conflict Diamonds, which compromise international peace and human security, as well as hampering economic and social development in affected countries.
