In 1943, a submarine returning from a secret mission is attacked, its vital cargo believed lost . . .
Three quarters of a century later, NUMA Director Dirk Pitt is asked to help locate a missing person: the scientist responsible for the design of the revolutionary Poseidon's Arrow submarine. This craft is so advanced and dangerous that any government would kill to possess it - and not just its designer has disappeared, so have the final plans.
But this is no simple search.
It leads Pitt from Washington to the Panama jungle, draws in the full resources of NUMA, and slowly unravels a deadly conspiracy which seeks to bring the world to its knees - and only Pitt can prevent it.
A non-stop page-turner filled with heart-in-the-mouth thrills, Poseidon's Arrow is Clive Cussler at his magnificent, peerless best.
