The Commodore

After several installments of gallivanting around the South Seas, Aubrey and Maturin return home to England, where the surgeon-cum-intelligence-agent discovers that his wife has disappeared.
As if such a domestic crisis weren't enough, the intrepid pair are also dispatched to the Gulf of Guinea (to suppress the slave trade) and to Ireland (to rebuff an impending French invasion).
O'Brian's stunning range, coupled with his mind-bending command of minutiae, explain why James Hamilton-Paterson has called him "the Homer of the Napoleonic Wars."
