It's been a week since Dept. Q dropped on Netflix, introducing us to Detective Carl Morck, Akram and Rose as they attempt to solve the case of Merritt Lyngard, a prosecutor who disappeared four years ago without a trace. And if, like us, you raced through the series, and are now wondering when you'll next get to see them in action, well then you're in luck. While we're still waiting for season 2 to be confirmed (hurry up, Netflix), you can read what cases the unlikely trio solve next because there are 10 books in the series the Netflix show is based on.

First published in Denmark in 2007, the Department Q books are written by Jussi Adler-Olsen and have since been translated and published all over the world. The first novel in the series, Mercy, follows a very similar plot to that of the TV show, except it and the subsequent novels are all set in Copenhagen.

The next nine books explore all the trio's backstories, while also seeing them solve a variety of cold cases. All 10 books are available to buy in the US and while we would recommend reading them in chronological order, you could also start with the case that sounds most intriguing to you. So here all the plots of the Department Q books by Jussi Adler-Olsen.
