This is easily one of the best books inthe Aubrey/Maturin series of O'Brian - set a few years after "Mauritius Command" it sends Captain Aubrey and faithful Dr. Maturin back into the landless, vast and eternally stormy seas of the southern Indian Ocean - in an old tired frigate of ill-repute, stuffed with a plague ridden crew, convicts for the Australian colony and a beautiful spy in the hold, as well as rotten timbers, a quarrelling set of officers and a tireless foe on their heels. More than enough to keep both the captain and the doctor/spy busy and on their toes, the dialogue loaded in the typical "low-key" way and the reader glued to the pages.
The running battle with the Dutchman is easily one of the best (and most remarkable deadly ) actions in the entire series.
Oh, and the readers get treated to some wrecking and life-boat frollicking, too. No more could be asked for.
