Robert Ludlum: The Cry of the Halidon

Alex McAuliff has received an offer he can't refuse: two million dollars for a geological survey of Jamaica's dark interior. All Dunstone, Limited, requires is his time, his expertise, and his absolute secrecy. No one—not even McAuliff's handpicked team—can know of Dunstone's involvement.But British Intelligence is aware of the deal and they've let Alex in on a secret of their own: the last survey team Dunstone dispatched to Jamaica vanished without a trace. Now it's too late to turn back. Alex already knows about Dunstone...which means he knows too much.From the moment he lands in Jamaica, Alex is a marked man. But who wants him dead? Dunstone? A rival company? Or British Intelligence? Here in an island paradise where even a beautiful woman might be a spy, every move could be his last, and his only clue to survival is a single mysterious word: Halidon.
