The Viscount’s Marriage of Inconvenience by Barbara Russell

England, 1882
Keith, a servant in a rich house, feels nothing but gratitude for the Sharpe family. They rescue him from a miserable life and welcome him into their home, and Miss Violante Sharpe teaches him how to read. She’s so kind and pretty that he can’t help but fall for her.
But when Keith learns that Mr. Sharpe is part of an anarchist organization planning to blow up a politician’s house and kill people, he doesn’t hesitate to warn the police, ready to pay the consequences.
Violante’s life goes from riches to rags after the police kill her father and storm Sharpe Manor. Discovering her beloved papa was an anarchist breaks her heart. If only Keith had talked to her instead of going to the police. Good thing she doesn’t want to see him again.
