Harper Lee: To Kill a Mockingbird 'sequel' to be published

An unpublished novel by Harper Lee is to finally see the light of day, 60 years after the US author put it aside to write To Kill a Mockingbird.

Go Set a Watchman, which features the character of Scout Finch as an adult, will be released on 14 July.

The BBC's Nick Higham said there had been a lot of mystery surrounding the fact Harper Lee had not published any more works.

"I think we can assume it will go like hotcakes," he said.
