Beloved British novelist Sue Townsend was writing a new Adrian Mole book at the time of her death.

The writer passed away on Thursday (10Apr14) at the age of 68 following years of health troubles, and it has now emerged she left behind a new installment in her Adrian Mole franchise.

Townsend was writing a book with the working title Pandora's Box which was due for publication later this year (14).

A spokesman for Townsend's publisher, Michael Joseph, says, "We can confirm that Sue was in the middle of writing the book. Her editor had seen what she describes as 'a few wonderful pages'. It was supposed to be out this autumn and we are very sad that we won't be able to show it to the world."

Townsend released her first Adrian Mole book in 1982 and the last installment, Adrian Mole: The Prostrate Years, was published in 2009.
