In Renee Knight's Disclaimer successful documentary maker Catherine starts reading a book she finds on her bedside table, only to discover that the main character is based on her, and the events of the book mirror something that happened long ago, and that she hoped would never be revealed to her nearest and dearest.
Disclaimer initially comes across as your average domestic psychological thriller, but it quickly becomes clear that Knight has crafted something sophisticated and different to the glut of Gone Girl imitations that have come out in the last couple of years.
Chapters alternate between Catherine, who is reluctant to reveal details about her past, and the writer of the book, whose motives are initially obscured. Disclaimer features two narrators who are both unreliable in their own ways, making it difficult to work out what really happened, but that's part of the joy of the book. And when the truth is finally revealed, it's nothing you could have imagined.
