Update: UK period drama Poldark has been renewed for a fourth season.
Series three will in the UK in June while a fourth has been commissioned, but there is speculation a fifth could be the final.
RadioTimes suggests the current plan is to make just two more runs covering the final six books and ending with series five. Series 3 covers books 5 & 6 of Winston Graham’s 12 book series.
“Series four has already been commissioned and the fifth looks like it could well be the last,” said a senior BBC source. “All good things must come to an end. Even Poldark.”
The BBC declined to comment officially on the claims but pointed out that series 5 had not yet been commissioned.
ABC is expected to screen Season 3 in Australia later this year.
