Lady Cecily Fitzhenry was ruined in the South Sea Bubble. Her husband, whom she was forced to marry by her archenemy Sir Robert Walpole as punishment for her support of a Stuart rebel, has speculated with her dowry. The only property left to her is a crumbling public house on the Great North Road.

Thanks to a wily lawyer, Cecily becomes the saviour of her country in a way she hadn't expected...
