Author Winston Graham, who wrote the hugely popular Poldark novels, has died aged 93.
Winston Graham lived in Cornwall for 30 years
The books were made into a hit 1970s BBC costume drama starring Angharad Rees, Robin Ellis and Ralph Bates.
A spokesperson for his publisher said he died on Wednesday after being unwell for a short time - but the cause of death was not made public.
His tales of Ross and Demelza Poldark have been translated into dozens of languages and the TV series were shown in 22 countries.
Set in 18th Century Cornwall, a county he lived in for 30 years, they examined the social relationships of the era between the oppressed poor and the wealthy land-owners.
Graham's original plan was to write three books focusing on the love triangle between the war hero Captain Poldark, cousin Francis Poldark and aristocrat Elizabeth Chynoweth.
But he extended the series as he became more interested in the society's wider tensions.
Outside the Poldark saga, Graham's best-known book was Marnie, which became an Alfred Hitchcock movie starring Sean Connery.

Ross Poldark was first published in 1945, followed by Demelza in 1946, Jeremy Poldark in 1950, and Warleggan in 1953.
The Walking Stick was made into a movie by MGM and starred David Hemmings.
In 2002, Graham announced that Bella Poldark, the 12th volume of the tales, would be the last.
He wrote 40 novels in total and was made an OBE in 1983.
