Undertow — Desmond Cory

Moreno, a psychopathic Spanish killer, is helped to escape from prison to aid KGB intelligence chief Feramontov recover the ‘Spyglass logbooks' which hold the key to political secrets hidden in a U-boat sunk at the end of World War II under cover of a marine biology research mission. But not only has Feramontov underestimated the violent appetites of the dangerous and unstable Moreno, but has unwittingly put his entire operation in the sights of freelance British special agent Johnny Fedora and his Foreign Office side-kick Sebastian Trout.

The violence escalates along the beautiful Mediterranean coast as Franco's police and intelligence services attempt to track Moreno, but it is left to Johnny Fedora to foil the KGB operation--and deal with Moreno--in a lethal scuba dive through the undertow into the deadly confines of a wrecked submarine.
