I Will Repay was written by Baroness Emmuska Orczy and originally published in 1906, this is a sequel novel to the Scarlet Pimpernel. The second Pimpernel book written by Orczy, it comes chronologically third in the series, after Sir Percy Leads the Band and before The Elusive Pimpernel. A notable error by Orczy comes when the climactic chapter ends at the grave of Abélard and Héloïse at Pere Lachaise cemetery; the cemetery was not founded until 1804, over ten years after the events of the story, and Abélard's and Héloïse's remains not moved there until 1817. The novel was adapted for film in 1923. Source: Wikipedia (en)
