Dennis Wheatley – They Found Atlantis (Arrow, 1958: originally 1953)
Blurb:
THEY WERE TRAPPED …. 900 fathoms under the sea.
This was the end of their wonderful expedition. Just a few days earlier they had embarked on a search for the lost continent of Atlantis with its rich treasure of gold and precious stones. Now death was just around the corner – they thought, but what awaited them was the most amazing sights and breathtaking adventures ever experienced by human beings.
