I wanted to love this - a cruise ship thriller described as Agatha Christie meets Succession, it sounded like a fun, escapist holiday read. It‘s gripping, pacy and kept me turning the pages. YBut the premise felt contrived & I didn‘t believe the friendship between Emily & Belle which is central to the book. The tycoon‘s family are all rude & unlikeable, a trope that didn‘t feel fresh & can be heavy going. It‘s action, not Christie-esque.
