Money to Burn by Asta Olivia Nordenhof, translated from Danish by Caroline Waight has a complicated, fascinating and unusual structure. As well as being about a fictional couple - Kurt and Maggie - it is about the narrator's (who is, I'm assuming, Nordenhof) investigation into insurance scam around the fire onboard a ferry called The Scandinavian Star in the 1990s, when 159 died. Kurt invests in the company that buys the ferry, and as well as learning all this, and having the narrator / Nordenhof interact with her characters, we get Kurt's and Maggie's backstory - which made me feel much more sympathetic towards the difficult characters they have both become in their adult lives. See? Complicated. But it really worked for me. I got Kurt and Maggie. The characterisation is wonderful, the true-crime element surprising, the narrator / Nordenhof's interruptions really interesting. I will definitely be reading the others (seven?) in the series.
