Ducos, like a predator watching its victim, stared at the woman.

She was beautiful, this Golden Whore. Men who saw her for the first time hardly dared believe that any woman was so beautiful. Her skin was as white and clear as the white pearl shells of the Biscay beaches. Her hair was golden. An accident of lip and bone, of eye and skin had given her a look of innocence that made men wish to protect her. Pierre Ducos could think of few women so little in need of protection.

She was French. She was born Helene Leroux and she had served France since her sixteenth year. She had slept in the beds of the powerful and brought from their pillows the secrets of their nations, and when the Emperor had taken the decision to annex Spain to his Empire, he had sent Helene as his weapon.

She had pretended to be the daughter of victims of the Terror. She had married, on instructions from Paris, a man close to the Spanish King, a man privy to the secrets of Spain. She was still married, though her husband was far off, and she bore the title that he had given her. She was the Marquesa de Casares el Grande y Melida Sadaba. She was lovely as a summer dream and as treacherous as sin. She was La Puta Dorada.

Ducos smiled. A hawk, high above its victim, might have felt the same satisfaction that the bespectacled French Major felt as he ordered his aide to send his compliments to the Marquesa with a request, which, from Pierre Ducos, was tantamount to an order, that her Ladyship come to his presence immediately.

La Marquesa de Casares el Grande y Melida Sadaba, smelling of rosewater and smiling sweetly, was ushered into Major Ducos’ bare room an hour later. He looked up from the table. ‘You’re late.’
