Though Christie wrote a great many standalone crime novels, Endless Night feels like a true departure, different to everything else she wrote before or since. It’s not a classic detective story with classic detective tropes, there is barely any criminal investigation and the crime itself happens almost three-quarters into the story. Back when I first read it as a teenager my reaction was ambivalent, but even then this eerie novel imprinted on my brain as much as the haunting passage from William Blake’s poem it takes its name from. Revisiting it now has cemented Endless Night as one of my Christie favourites.
