Reclusive author Harper Lee has asked a U.S. judge to reinstate her lawsuit against museum bosses in her Alabama hometown after a settlement deal between the two parties fell through.

The To Kill A Mockingbird writer took officials at the Monroe County Heritage Museum in Monroeville to court last year (13) over allegations they were exploiting her name and the title of her Pulitzer Prize-winning novel on souvenirs without permission.

In February (14), representatives for both sides announced a private agreement had been reached, but it appears the deal is now off.

Lee's lawyer claims museum officials angered the famous author by asking for additional terms which they had not agreed on in the original settlement, and now she is determined to follow through with her suit.
