Sylvie Delamare's great-uncle Sir George sends her a mere £20 - claiming it to be a whole half of her inheritance - and she's infuriated. Her parents had been wealthy, so she wants to go and confront him in Norfolk. Meanwhile, she is invited to visit Lady Carstairs, her friend's aunt in London, to be presented. However, Sir Randal is suspicious of Sylvie, after seeing her with Monsieur Dupont, who he suspects is one of Napoleon's spies. Then when Sir Randal follows Dupont, he meets Sylvie in Norwich on her way to see Sir George. And when he offers her a lift - he becomes embroiled in her affairs.
