Lady Horcania Rajhill, Baroness Rajhill

Lady Rajhill is a wealthy noblewoman, step-sister to Lady Andromeda Twistatalaught, and married to Rudyard Rajhill, Baron Rajhill. An extremely uppity and arrogant woman, she and her husband have a joint fortune of £89 billion, making her the wealthiest woman in the world. In Devonshire, she provides the perfect antagonist to Andromeda, playing upon her anxieties about keeping a good reputation.

Biography
Rajhill was born in 1975 in Belgravia, London to Sir William Merithel and Lady Patricia Merithel (née Harper-Dowles). Merithel being a successful investment banker with a small fortune of £20 million, Rajhill grew up living a comfortable life, living in a large Belgravia townhouse, a country manor and a villa in Cannes, France. Rajhill attended St Paul's Girls School in London, from 1985 to 1993, whilst her parents were divorced and her father moved to Cannes, France. After school, Rajhill moved to Cannes for one year to live with her father, his second wife, Renée Gabrielle de Marcilliac (née Dubois), and their three year old daughter, Lady Andromeda Twistatalaught (née Merithel). Rajhill received a £10 million fortune from her father, which she took with her to Northamptonshire and then New York.

However, in December 2015, Rajhill returned from New York to her father's Belgravia home, in which she lived for the next seven years of her life. In the Devonshire Christmas Special we first meet Lady Rajhill (then Lady Merithel), who visits her step-sister Andromeda in early January 2016, only to leave on the day of her arrival due to a fire at Andromeda's house.

In 2022, Rajhill marries Rudyard Rajhill, Baron Rajhill - an Indian businessman, life peer, and the wealthiest man in the world with a fortune of £89 billion. Rajhill describes in Sibling Rivalry to Andromeda's step-brother, Flavio de Marcilliac, how after her marriage, she and her husband bought "a dozen or so houses" in London, and how they "live all over the place now."

However, by Episode 5 of Season 5, it is revealed that Rajhill has an entirely different and much darker identity. Since Hooligans and Hacklesbys, she has been working with a professional hacker, Mr Teef, and gunman, Gonzalez, to break into her husband's company, the Rajhill Institute, and expose and sell secrets for billions of pounds to people across the world. However, when she is caught by the police, she is charged with data theft, attempted murder, possession of a shotgun and identity fraud, resulting in a lifetime prison sentence.
