CRY OF THE HALIDON, THE(ISBN=9780553576146)

　　First published under the pseudonym Jonathan Ryder, The Cry of the Halidon is vintage entertainment from suspense master Robert Ludlum. -- Review

　　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 anisland 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.
