This is an epic novel of sea-faring adventure set in the 19th century charting the life of Robert Fitzroy, the captain of `The Beagle` and his passenger Charles Darwin. It combines adventrure, emotion, ideas, humour and tragedy as well as illuminating the history of the 19th century. Fitzroy, the Christian Tory aristocrat, believed in the sanctity of the individual, but his beliefs destroyed his career and he committed suicide. Darwin, the liberal minor cleric doubts the truth of the Bible and develops his theory of evolution which is brutal and unforgiving in human terms. The two friends became bitter enemies as Darwin destroyed everything Fitzroy stood for.
