Publisher's Synopsis
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 only has its designer disappeared, but so too have the final plans.
