Gallows on the sand

de Morris West

Renn Lundigan found a gold coin on a tiny island off Australia's Barrier Reef. His research led him to believe that a galleon, containing twenty chests of minted Spanish gold, had foundered on the outer reef of the island. Renn realises the dangers involved in diving to find the wreck, but he soon has more than the sea to contend with when others discover his secret.
