Lord Tony's Wife, by Baroness Orczy

is a sequel book to the classic adventure tale, The Scarlet Pimpernel. It was first published in 1917.

The year is 1789 and Pierre Adet, a young French peasant, is incensed at the unfair treatment of the local peasantry, who are no better off than slaves to the local aristocrat. His brother-in-law is about to be hanged for poaching two pigeons from the woods belonging to the Duc de Kernogan in Nantes and this proves the final straw.

After months of planning Pierre leads a mob against the Duc against the advice of his father. (Wikipedia)
