A lawyer-turned-writer has scooped a major book award.

Sara Collins, 47, won the prize for best first novel in the Costa Book Awards.

Winners are also awarded in the novel, biography, poetry and children’s book categories.

Collins’s debut The Confessions Of Frannie Langton features a “twisted love affair” between a Jamaican maid and her French mistress in Georgian London.

The “gothic romance” was inspired by the story of a Jamaican boy, Francis Barber, sent into service in the household of Samuel Johnson.

Johnson wrote that Barber had been “given me by a friend” and the idea that a child could be given as a gift in England formed the springboard for the book.

Jamaican-born Collins worked in the Cayman Islands as a dispute resolution lawyer for 17 years and was also involved in human rights advocacy.

She wanted to “dispel the myth that the black presence in England started with Windrush”, with the book.

Debut authors scooped two other categories, with Jasbinder Bilan winning the Children’s Book Award with her first novel, Asha And The Spirit Bird, “a thrilling adventure set in contemporary India”.

Mary Jean Chan won the Poetry Award with her debut collection, Fleche,  exploring “themes of multilingualism, queerness, psychoanalysis and cultural history”.
