1926, Kent. Chef Nell Drury is busy with preparations for Lady Ansley's luncheon to welcome Wychbourne Court's new neighbours, Sir Gilbert and Lady Saddler. The couple's arrival has led to much rumour and intrigue swirling around the village, particularly with regards to the mysterious Lady Saddler.

Sir Gilbert belongs to a new artistic movement, the Artistes de Cler, and is organizing a summer festival in the grounds of Spitalfrith Manor, where the Clerries will gather to reveal their Africa-inspired paintings. The whole village is invited and buzzing with excitement. But at the festival itself, Nell witnesses some strange and disturbing events, and when a terrible discovery is made the following day, she is horrified to learn that Lord Ansley's valet has been arrested. Can Nell clear his name while also confronting a face from the past?
