In 1965, a fortune-teller told Frances Adams that one day she'd be murdered. Frances spent sixty years compiling dirt on every person she met, just in case they might turn out to be her killer. But none of her friends or family took her seriously. Until she was dead.
When her great-niece, Annie, arrives in Castle Knoll, she finds herself a participant in a dangerous game. Frances' will stipulates that the person who finds her killer will inherit her millions. And in the heart of her sprawling country estate lies an eccentric library of detective work, where the right person could step in and use her findings to solve her murder.
