Back in New York, Brooke sets out on the trail of her very different paternal ancestry, the family of her paternal grandmother, the glamour heiress Marina Torlonia.

But it doesn't end there - on the trail of yet another illustrious ancestor, the mysteriously titled 'Madame Royale', Brooke heads to Paris and the very heart of French nobility.
