It was the book that promised to offer the rarest of glimpses into the life of Harper Lee, the celebrated but reclusive author of To Kill A Mockingbird who despite her fame has shunned the limelight and still lives in her home town of Monroeville, Alabama.
It had even earned the notoriously shy writer's blessing, so its publishers said.
But not according to Lee. The author has chosen the week that The Mockingbird Next Door: Life With Harper Lee is released in America to launch a scathing attack on the book, written by Marja Mills, a former Chicago Tribune journalist who became her neighbour in 2004.
"Miss Mills befriended my elderly sister Alice," she said in a statement. "It did not take long to discover Marja's true mission; another book about Harper Lee. I was hurt, angry and saddened, but not surprised. I immediately cut off all contact with Miss Mills, leaving town whenever she headed this way."
It is a long way from what Penguin, the book's publishers, said would be an intimate account of the author and her sister's day-to-day existence sharing coffees at McDonald's, visiting the local Laundromat, eating catfish and feeding ducks. Lee, who goes by her first name of Nelle, was said to have "shared her love of history, literature, and the Southern way of life with Mills, as well as her keen sense of how journalism should be practised".
"As the sisters decided to let Mills tell their story, Nelle helped make sure she was getting the story - and the South - right," publicity materials said. "Alice, the keeper of the Lee family history, shared the stories of their family."
