In 1965, when a fortune-teller at an English country fair predicts that Frances Adams would be murdered, she spends her lifetime in fear, collecting information on every person she comes across, trying to avoid her own demise. Decades later, her great-niece Annie Adams receives a letter asking her to come to Castle Knoll in Dorset to discuss Frances's will. However, by the time Annie arrives at Frances's sprawling country estate, she is found dead in her library. According to Frances's will, she expected to be murdered and whoever solves her murder within a week would inherit all her property worth millions. As Annie sets out to trace the murderer, piecing together clues by reading Frances's journal, she finds that a lot of locals coveted her great-aunt's property. Then there is one of her suspects, Saxon, who is also trying to solve the murder and inherit the property before Annie does. In this first book of the Castle Knoll Files series, while Annie is getting to the bottom of the mystery, she is worried that she might be the next one on the murderer's list.
