The Lady and the Duke

Grace Elliott, a well-connected English lady, is living in Paris at the time of the French Revolution. She was once the lover of the Duke of Orléans, cousin of King Louis XVI, who remains her closest friend and confidant. However, whilst the Duke supports the Revolution, Grace's sympathies are with the king and his family. Without the Duke knowing, she risks her own life to save a nobleman from arrest and certain death on the guillotine. Later, she is appalled when the Duke casts a decisive vote which sanctions the king's execution. With Paris in turmoil, Grace finally decides to return to England, but before the Duke can obtain a passport for her, she is arrested when a compromising letter is discovered in her house...
