Adam Deveril, the new Viscount Lynton and a hero at Salamanca, returns from the Peninsula War to find his family on the brink of ruin and the broad acres of his ancestral home mortgaged to the hilt. It is Lord Oversley, father of Adam's first love, who tactfully introduces him to Mr Jonathan Chaleigh, a City man of apparently unlimited wealth with no social ambitions for himself, but with his eyes firmly fixed on a suitable match for his one and only daughter.
