To his enormous delight Tim is asked to help sail a yacht from the Netherlands to Greece. For the skipper, a millionaire called Robert, Tim’s negligible sailing experience doesn't appear to present any problem at all. Once aboard, Robert keeps Tim and his friend Julia entertained with the most captivating stories.


However, as the journey progresses, Robert starts to act rather strangely. Little by little Tim begins to realize that Robert is not quite the man he appears to be to the outside world.  Could it be Tim’s imagination running riot after weeks at sea, or might he actually be dealing with a psychopath?


Black Waves is a thriller that gets right under your skin. A story about trust in human goodness, but also about people who present themselves differently to how they really are deep inside.
