The two couples are friends, but things get dodgy when Kit disappears and the police suspect Jamie of being involved. Although there is a solid mystery that is satisfactorily resolved, Candlish is at her best when observing the toxic tensions between generations and the issues between people from different income groups. Overall, it’s another winner.
What The Other Passenger does have is twists, the first of which is particularly well done, although subsequent reveals are less surprising, while the lack of characterisation means that things run out of steam in the final chapters. But this is a satisfying read and perfect for a TV adaptation. With its tight cast and stylish backdrops, sharp plotting and clear narrative voice, I’ll be amazed if we don’t see The Other Passenger on screen before long.
