The Ghostwriter by Julie Clark

Olivia is a ghostwriter, helping people tell their life stories. When her estranged father Vincent, a best selling horror writer, has his publisher reach out to Olivia asking if she'll help him finish his next book, Olivia agrees-- except this story is not fiction, it's a story from almost fifty years ago when Vincent's siblings Danny and Poppy were murdered. The crime was never solved. Olivia has grave misgivings about taking the job, but she's in need of money, since she was sued by a fellow writer and owes him half a million dollars. When Olivia arrives at Vincent's home, she finds him in bad shape. He has been diagnosed with Lewy body dementia and has a caregiver, Alma, who has been helping him out. In addition, Olivia's and Vincent's relationship hasn't been great since he sent her to boarding school in France when she was a teenager. As Olivia and Vincent begin to collaborate, it becomes clear that the book needs a lot of work and more questions than answers about what happened all those years ago are raised. Who killed Danny and Poppy? Was it Vincent or someone else? Julie Clark keeps the reader turning the pages to find out what really happened.
