Dominic mentions he reviewed this book for the Sunday Times and gave it a rave review. He describes it as telling the story of Portuguese expansion as 'a rip-roaring, rollicking adventure story.' The book is referenced multiple times throughout the episode for details about Vasco da Gama's voyage, the departure scene from Lisbon, and even ends with a reference to Portuguese custard tarts dusted with cinnamon as a symbol of the spice trade.
