A BESTSELLING author who doubles up as a physician will be meeting fans and giving away a signed copy of her new book to a lucky winner.

On August 30 Tess Gerritsen will appear at Waterstones Broad Street from 12.30pm for the release of her latest book 'I Know a Secret'.

Gerrisen has won a large audience for her thrillers starring homicide detective Jane Rizzoli and medical examiner Maura Isles, books that inspired the hit TV series Rizzoli & Isles.

As an anthropology student at Stanford University, she catalogued centuries-old human remains, and she continues to travel the world, driven by her fascination with ancient cultures and bizarre natural phenomena.

'I Know a Secret' takes up the grizzly baton and throws the reader into a world of detective drama and mistaken identities.

To win a signed copy of the new book and a chance to meet Gerritsen, subject to the event running to schedule, send the answer to the following question along with your name, address, telephone number and email address to events.reading@waterstones.com or send to Tess Gerritsen Competition, Waterstones Reading Broad Street, 89a Broad Street, Reading RG1 2AP.

What is the name of Tess Gerritsen's new book?

The competition closes at midnight on Wednesday 23 August. The winner will be notified by Thursday 24 August.
