Harper Lee had planned more books, says friend Joy Brown
Fifty-five years after writing To Kill A Mockingbird, author Harper Lee is finally publishing the novel which started it all.
Go Set a Watchman was written in the mid-1950s, but Lee was persuaded by her editor to use some of the story's flashback sequences for a different novel.
It was rediscovered when her lawyer found it with the original To Kill a Mockingbird manuscript in a safety deposit box.
The novel, which is already the most pre-ordered title since the final Harry Potter instalment, will be released on 14 July.
Will Gompertz reports.
