The adventure continues… At the time of his death, Patrick O'Brian had begun to write the twenty-first book in his famous and much-loved Aubrey-Maturin series. The chapters he left behind are presented here, both in printed version and a facsimile of his manuscript, which goes several pages beyond the end of the typescript and includes O'Brian's own marginal notes. The story picks up from the end of Blue at the Mizzen when Jack Aubrey receives the news, in Chile, of his elevation to flag rank: Rear Admiral of the Blue Squadron, with orders to sail to the South Africa station.
