Mystery, crime-thriller girlies assemble! New York Times bestselling author Louise Penny is back with a new book this year, and Chief Inspector Armand Gamache of Sûreté du Québec is back on the case. The Lone Wolf is the twentieth (technically, twenty-first if we’re counting her short novella) of the Armand Gamache book series, and if you’re unfamiliar, it’s about time that you’ve caught on.

Unlike Sherlock Holmes or Hercule Poirot, Gamache doesn’t have the big ego but is a principled and compassionate investigator with a strong moral compass. While his empathy earns him the trust of victims and suspects, it also makes him appear weak—especially in the face of corruption and ruthless ambition within his own police force. But these characteristics are what make Gamache such a compelling protagonist and endearing to any reader who decides to pick up one of Penny’s books.

I know 20 books sounds like a lot, but there’s no need to feel any pressure. What’s great about mystery book series is that, for the most part, each novel is a self-contained mystery. (Think Nancy Drew or The Hardy Boys.) Of course, it can be more rewarding to read all books in succession, just to catch up on some longer-term plot lines. In any case, it’s worth noting all of Penny’s works. So here’s a guide to all of Louise Penny’s books in order of release.

Set once again around the holidays in the picturesque, Quebecois village of Three Pines—this time around Christmastime—Gamache finds himself with another mystery in his hands.

They decide to spend it at Manoir Bellechasse, an isolated, luxurious inn not far from the village of Three Pines. But they’re not the only ones celebrating at the inn.

This centers around the death of a stranger, whose body was found at the beloved Olivier’s Bistro, run by the well-liked villager Olivier Brulé. Gamache uncovers that the unknown victim was a hermit living in a hidden cabin in the woods outside of Three Pines, and collected priceless treasures and artifacts. As the Chief Inspector digs deeper into Olivier’s story about the mysterious death, he can sense that he’s not telling the whole truth. Why were his fingerprints all over the victim’s cabin outside of town?

The Hangman

The Hangman is the unofficial seventh book in the Gamache mystery book series. But it isn’t officially counted (and considered book 6.5) because it is a rather short novella, as opposed to a full-blown novel. It’s a short and easy read that could definitely be finished in one sitting. A jogger runs in the woods of Three Pines and discovers a dead body hanging from a tree. Though this was made to look like a suicide, Gamache soon uncovers some truths about this outsider visiting the village, and finds connections to the past that reveal there is so much more to the story than meets the eye.

Bury Your Dead

On break from duty in Three Pines, Chief Inspector Armand Gamache heads north to celebrate the Winter Carnival, and recover from a previous investigation that went wrong. But, of course, it seems like violent death follows him even when he tries to go elsewhere. This time, it’s an academic from the Literary and Historical Society searching for answers. While away, he also receives word from back home that Olivier was recently convicted of murder—even when everyone, including Gamache, believes him to be innocent. Solving this case becomes a more urgent matter than ever.

A Trick of the Light

Lillian Dyson was a former art critic who made and broke artists’ careers. It seems that her sometimes-harsh reviews ultimately led to her demise as her body was found among the bleeding hearts and lilacs of artist Clara Morrow’s garden in Three Pines. This puts a halt to the celebrations of Clara’s big solo show at the Musée in Montréal. Gamache soon finds that dealing with people in the art world can be very tricky. And that what might seem like the gleaning truth might just be a trick of the light.
