An exhibition of Christie's 'secret' letters to her longstanding publisher HarperCollins is on display in the Walled Garden, created to celebrate HarperCollins' 200th anniversary.

The exhibition showcases photographs and letters unearthed from the HarperCollins archive, and show Agatha and 'Billy' Collins, former chairman and publisher of Collins, discussing jacket designs, plots and publishing schedules.

First nights, publishing parties and the difficulty of obtaining tennis balls during the war are all covered in their letters, and show the professional relationship develop into a friendship over time.
