The Cry of the Halidon Ludlum, Robert

A geologist. A revolution. And a 300-year-old secret buried in the mountains of Jamaica. Alexander Tarquin McAuliff arrives on the island for what should be a straightforward survey expedition, but nothing in a Ludlum novel is ever straightforward. Within hours, he's caught between British Intelligence, the CIA, and a mysterious force called the Halidon — a secret society guarding something the world's superpowers will kill to possess. The jungle becomes a maze of double agents, shifting loyalties, and escalating violence. Ludlum trades Cold War Europe for the Caribbean heat, delivering his signature conspiracy-thriller mechanics with tropical paranoia. If you're here for labyrinthine plots, relentless pacing, and the slow realization that everyone might be lying — you're in the right place. Best read with rum and a healthy distrust of authority.
