The Dead of Winter

Nicola Upson was born in Suffolk and read English at Downing College, Cambridge. Her debut novel, An Expert in Murder, was the first in a series of crime novels whose main character is Josephine Tey, who - along with Agatha Christie - was one of the masters of Britain's Golden Age of crime writing. There have been eight books in the series, of which Nine Lessons was shortlisted for the CWA Historical Dagger in 2018.
She lives with her partner in Cambridge and spends much of her time in Cornwall.
