Jeffrey Archer, the British author and former politician, has died at age 86. Archer sold more than 300 million books across a five-decade writing career. His final work, a novel titled Adam and Eve, was scheduled for release later this month, according to the BBC.

Archer held multiple roles throughout his life beyond his prolific literary output. His books reached audiences worldwide and established him as one of the most commercially successful authors of his era. The timing of his death comes just before the publication of what would have been his latest novel.
