Harper Lee's Lawyer Reveals 'To Kill A Mockingbird' And 'Go Set A Watchman' Author May Have Penned A Third Book

Readers who were left stunned by the revelation that Harper Lee had penned a second novel might want to sit down for this news, as it’s been suggested that the ‘To Kill A Mockingbird’ and ‘Go Set A Watchman’ author may have penned a third book.

The writer’s second novel - which was technically her first - was released on Tuesday, after being discovered in a safety deposit box at her retirement home.

Now, Tonja Carter, the lawyer responsible for the publication of ‘Go Set A Watchman’, has suggested that Harper could have written a third, as-yet-undiscovered novel.

In a bid to dispel controversies surrounding the ‘Go Set A Watchman’ publication, Tonja penned an editorial for the Wall Street Journal.

In it, she claims to have found a third stack of papers in Harper’s possession, which may well be another book.

Speaking of when she discovered the ‘Watchman’ manuscript, Tonja writes: “And something else was in the Lord & Taylor box. The manuscript for ‘Watchman’ was underneath a stack of a significant number of pages of another typed text.”

She goes on to discuss the latest book’s publication, before returning to the topic of the other mystery manuscript, writing: “What of the other pages that have for decades sat in the Lord & Taylor box on top of ‘Watchman’? Was it an earlier draft of ‘Watchman,’ or of ‘Mockingbird,’ or even, as early correspondence indicates it might be, a third book bridging the two? I don’t know.

“But this much I do know: In the coming months, experts, at Nelle’s [Harper’s] direction, will be invited to examine and authenticate all the documents in the safe-deposit box."

"Any uncertainty about the ‘Mockingbird’ manuscript removed from the mailing envelope and the mysterious pages of text in the Lord & Taylor box will be addressed," she continues. "As we celebrate the publication of ‘Go Set a Watchman,’ history demands no less from us.”

The early reviews of ‘Go Set A Watchman’ have been mixed, and plenty of fans have shared their fears following the news that Atticus Finch has grown older into a bigoted man.

The early publication of the book’s first chapter also left fans stunned, when it was revealed that one of the key ‘To Kill A Mockingbird’ characters is no longer alive.
