Official Description Edit

"Countess Musgrove is a French [1] socialite, who uses her beauty to beguile influential men to improve her position in society. Well known for her wild parties."[2]


Countess Musgrove is an aristocrat who comes from New Orleans, determined to have a part in the power struggles between Americas and British Empire.

Appearance and PersonalityEdit

Countess Musgrove, whose birth name is Genevieve Decoux, is an eccentric noblewoman capable of considerable subterfuge. As a secret agent for Americans, she is a skilled liar. The Countess is a woman in her forties, with fair skin, mahogany hair and a heart-shaped face. Her clothing is lush and sophisticated, as befits the aristocracy.


Countess Musgrove held a soiree to which he invited all the London society, including Geary spouses, and James Delaney, who participated together with Lorna Bow. The Countess, once left alone with James during a game, was revealed as Carlsbad by James, and the two discussed the terms of their agreement about the trade. (Episode 4)

During a tasteless meal with her husband, the Countess received a visit from James Delaney. The two, strolling in the garden, confirmed the points of their alliance and the countess tried in vain to obtain information about Nootka Sound, revealing at the same time be just a spokeswoman with no decision-making powers within the network of spies. (Episode 5)

Alarmed by the recent arrest of James Delaney by the Crown, the Countess hastily burned some incriminating documents of her involvement with the dense network of American spies. (Episode 7)

While the Countess was playing cards with some ladies-in-waiting in the parlour of her palace, she was visited by Lorna Bow who passed herself off as a cosmetic saleswoman. The two women put aside and the Countess pointed the blade of a dagger pulled from her sleeve to Lorna Bow's throat. The brazenness of the Countess broke down when she was blackmailed by the visitor, who claimed to be ready to ensure that the Countess would have been exposed as a spy if Lorna had not come back safe and sound. (Episode 8)

Episode AppearancesEdit

Season 1


  • Countess Musgrove is the person behind the fictitious identity known as "Carlsbad", as revealed in the fourth episode.
  • She is originally from New Orleans, according to research by James Delaney.
  • In Episode 8, when Countess Musgrove is holding a knife on Lorna Bow's neck, you may notice that the Arabic word for "Allah" (in Arabic: الله) is engraved on it. Allah is one of the words used by the followers of the Islamic religion to refer to God of the Abrahamic religions.


  1. Although James Delaney states that she is from New Orleans, the official biography attests Countess Musgrove as a French socialite. Considering that at the time Louisiana was a French colony recently sold by Napoleon to the American States in 1803, and her French name, the official biography released by the BBC does not contradict what was said in the series.
