It’s hard to imagine a summer read better tailored to Crime by the Book than a Scandinavian psychological suspense novel, aka a combination of my two favorite kinds of crime books—and that’s exactly what readers will get in THE BOY AT THE DOOR by Alex Dahl. A binge-worthy story of suspense with dark and weighty undercurrents, Dahl’s first novel strikes an excellent balance between the melancholy and gloom of Nordic crime and the breezy pacing of your favorite beach read. Yet, despite its well-deserved “binge-read” status, THE BOY AT THE DOOR tackles genuinely difficult themes: most prominently, addiction and the pressures of motherhood take center stage here. It’s a winning combination, and, set against the atmospheric and picturesque backdrop of Scandinavia, Dahl’s tense and menacing story of familial suspense is a summer standout. Add this to your summer reading list and set aside a weekend to tear through its addictive and taut interpersonal mystery.
