A Civil Contract — Georgette Heyer

Adam Deveril, is one of the Duke of Wellington's captains, and a hero at Salamanca. When his father, a crony of the Prince Regent, is killed in the hunting field, Adam became the 6th Viscount Lynton of Fontley Priory, Lincolnshire.

But Adam didn't reckon with the Jenny nobody knew, or the unknown quality that lay hidden behind her demure and plain facade, who bring him comfort and eventually more....
