The author has a long list of books featuring "Sharpe."

In this one, he is returning to England from India in 1805; lovely lady on board ship; captured by French; ends up linked with Nelson at Trafalgar while dealing with French intriguers.

Cornwell always has good detail in these historical novels. "Line ahead," for example.
