If there’s one thing I love as a reader, it’s finding a crime fiction series that I can’t put down. There’s something so special about finding a fictional world that you never want to leave, and if you’re in the market for a crime fiction series to sink your teeth into while you stay home, you’ve come to the right place. In this blog post, I’m rounding up my personal favorite crime fiction series—the series I personally come back to over and over again. As you’ll see in this list, my personal tastes skew Nordic. You’ll find here a whole assortment of (if I may say so myself!) top-notch Scandinavian crime series to immerse yourself in this spring, and sprinkled in among these Nordic picks are a number of excellent serial killer thrillers and police procedurals from elsewhere in the world, too. These books have a lot of differences—some are fast-paced, some are slow-burns; some are gritty and violent, some are stylish and refined—but they are all staples of my crime fiction library, and books that I would highly recommend to any crime reader.
