They Found Atlantis
by Dennis Wheatley
Atlantis: for centuries the magic of that name has haunted man's imagination. Now, an incredible expedition is being prepared. Its destination: the final resting place of the ancient gold-encrusted city – one mile beneath the surface of the sea. For the lovely Camilla and her band of adventurers the days to come are full of danger. Ahead lies the silence of the unknown Deeps – and a nightmare of terror and betrayal.
