Florence finds herself emotionally involved in a case when a former schoolmate, Esther Monroe, is found dead at the foot of a cliff during a literary festival. The prime suspects for the murder include Sylvie Baptiste, writer of the infamous local novel "The Flame Tree"; her assistant, Patricia Lawrence; and festival organisers Anna and Oliver Wolf. Whilst searching for possible witnesses to the murder, Dwayne and JP come across a frightened woman living in a wooden shack on the outskirts of Sylvie Baptiste's estate. When Florence discovers that the woman may infact be Sylvie's long-lost sister Lizzie, a possible motive for Esther's murder comes to light.
