Laura Thompson attended stage school and at the age of sixteen won an exhibition to read English at Oxford. Her first book, THE DOGS: A PERSONAL HISTORY OF GREYHOUND RACING, won the Somerset Maugham Award. In her twenties she wrote extensively about sport and became a contributing editor to Esquire. She also wrote two books about horse racing: QUEST FOR GREATNESS, the story of her favourite racehorse Lammtarra, and NEWMARKET, a history of the town where she lived for some years.
In 2003 she wrote LIFE IN A COLD CLIMATE, a biography of Nancy Mitford, which was reissued in early 2015. This was followed by AGATHA CHRISTIE: AN ENGLISH MYSTERY, the first major biography of Christie for more than twenty years.
In 2014 she wrote A DIFFERENT CLASS OF MURDER: THE STORY OF LORD LUCAN, for which she was given much previously unheard information, including a solution to the forty-year-old mystery.
Among various TV appearances she has presented a BBC4 film BACK TO THE BARRE, about her return to ballet in adulthood, and most recently was chief interviewee in a major documentary about Agatha Christie for Japanese NHK television. She is a contributing editor to Town and Country magazine.
Her latest book, THE SIX, tells the story of the Mitford sisters and became a New York Times best seller in October 2016.
She is currently writing a crowd-funded memoir of her publican grandmother, THE LAST LANDLADY (Unbound), and will follow this with a re-examination of the famous 1922 Thompson-Bywaters murder case (Head of Zeus). Both books are projected to be published in 2017.
