Over the next five weeks, the League rescues many potential victims of the guillotine in Paris ("The Rescue"). The furious Robespierre orders Chauvelin to discover the identity of the Scarlet Pimpernel with the help of a Belgian spy named Grappin (Percy in disguise). Frustrated, Chauvelin vows to succeed ("Falcon in the Dive"). Back in England, Marie, Marguerite's old costume designer and best friend, has come to the Blakeney estate and is painting Percy's portrait. The Blakeneys' maids gossip about the Scarlet Pimpernel
