|The Hessen Conspiracy: nineteen forty-five - Castle Kronberg, outside Frankfurt, is turned into a 'country club' for victorious American officers. The cynical Colonel Jack Durant
and the dazzling beautiful Lieutenant Kathleen Nash uncover the crown jewels of Germany - more diamonds, rubies, emeralds, sapphires and pearls than are gathered in any
one place outside the Tower of London. Nash and Durant manage to get the gems to New York, where they must deal with gangsters to fence the loot.
