It's an offer Alex McAuliff just can't refuse: two million dollars for a geological survey of Jamaica's dark interior. All Dunstone Ltd. asks for in return in his time, his expertise, and above all his absolute secrecy. No one is to know of Dunstone's involvement - not even McAuliff's handpicked team. But others are aware of the deal: British intelligence knows and they've let Alex in on a little secret of their own: the last survey team sent to Jamacia by Dunstone vanished without a trace. For McAuliff it's too late to turn back. Alex already knows about Dunstone...which means he already knows too much. The moment Alex arrives in Jamaica, he is a marked man. But who wants him dead? Dunstone? A rival company? British Intelligence? Here on this island paradise, a beautiful woman could be a spy and every move could be his last. McAuliff's only clue to survival is a single mysterious word: Halidon.
