'A riveting detective story … Revelation follows revelation.' – Benedict Allen, author, explorer and TV presenter

James Fitzjames was a hero of the early nineteenth-century Royal Navy. A charismatic man with a wicked sense of humour, he pursued his naval career with wily determination. When he joined the Franklin Expedition he thought he would make his name; instead the expedition completely disappeared and he never returned. Its fate is one of history's great unsolved mysteries, as were the origins and background of James Fitzjames – until now.

Fitzjames packed a great deal into his thirty-two years, from trips down the Euphrates to fighting with spectacular bravery in Syria and China. But he was not what he seemed. He concealed several secrets, including the scandal of his birth, the source of his influence and his plans for after the Franklin Expedition.

In this definitive biography of the captain of HMS Erebus, William Battersby draws extensively on Fitzjames' personal letters and journals, as well as naval records, to strip away 200 years of misinformation, enabling us to understand for the first time this intriguing man and his significance.
