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.
