Agree Katherine, didn't like the others so much.
I enjoy Daphne du Maurier's historic ones, eg The Glassblowers. Rosemary Sutcliff's The Rider of the White Horse about Thomas Fairfax, Cromwell's General of Horse, is excellent.
I.found Pargeter lacking in humour, the lighter stiff, but perhaps that was just the age I read it.
If you like the navy, then obviously the Hornblowers and also what's his name, about Maturin.
For sentimental but charming, The Dean's watch by Elizabeth Goudge, ditto The White Witch. And the one about New Zealand .
If you like the army, the The Spanish Wife and An infamous army by Georgette Heyer. The latter used to be used ny Sandhurst to describe the Battle if Waterloo.
