7 Books Like The Decagon House Murders

I got this novel for my wife, but once I read her the beginning, she had to wait until I finished it before she could read it. It’s one of those books. It won a lot of awards when it was published and it became a Broadway play, and I can see why. Christopher Boone is on the spectrum, a teenager who doesn’t understand lies, emotions, and dislikes being touched. He does understand numbers, including prime numbers into the thousands, and knows all the countries and their capitals. He lives with his father, and when a neighbor’s dog is murdered, he sets out to investigate who did it. It’s not a simple story, but it’s told in a simple way that is easy to read, and a true page-turner. I like to find books that make you want to forgo television and this is one of them. I told my… show more.

This is a great historical fiction novel set in Turkey and France during the Holocaust. It was a really interesting way to view the events from a different cultural perspective than my own.

Edogawa Rampo is the father of Japanese detective fiction, and this macabre short story collection is a perfect introduction to his work. While not detective stories per se (he’s written some that are), these stories showcase a series of works that are fascinating, varied, dark, and very fun to read. 

Borrowing from elements from Western Silver Age detective fiction but adding elements of the grotesque and twisted, he is very distinct from all the Western mystery fiction I’ve read from a similar era. Since detective fiction formally started with Edgar Allen Poe and his C. Auguste Dupin in macabre stories, this seems a throwback to that storied history for me.

I like macabre mysteries with compelling hooks and clever resolutions that blow my mind, and this book does exactly that. Japan has a long tradition of writing “fair play” mysteries, which they call honkaku novels. These borrow from the Golden Age of Detective Fiction in the vein of Agatha Christie but certainly are their own category. 

These novels are like puzzles, focusing on the rules of fair play by giving readers all they need to figure out the mystery. This story was my first honkaku story and is only the length of a novella (like many honkaku novels), and it’s also rather dark, which I enjoy since I like horror as much as mystery.

This 90s manga series is one of the first proper murder mystery manga. While it’s aged a bit and not a honkaku that readers can solve, it borrows a bit from some famous Japanese honkaku novels and might be a good introduction to Japanese murder mystery fiction. Despite the homages, this is distinctively its own story.

As is commonly done in Japanese mysteries, most involve a seemingly impossible murder in a remote location with a long list of shady suspects. While teenage detective Kindaichi Hajime tries to solve the case, more murders happen. The stories are creative, and the solutions are, too—this series often has more macabre moments but is often sympathetic to the killers.

This is a fair-play honkaku novel that involves a twist with the supernatural—in this case, zombies. In Japan or otherwise, most detective fiction tends to avoid the supernatural. Still, zombies actually do behave predictably, so they can be used in the way a murder weapon can. 

Again, you can also solve this mystery before the “detective reveal,” which I didn’t manage to do, but the solution also involves some clever tricks. My reason for recommending this is the use of zombies (to besiege a manor where the characters are holed up), giving this detective story a fresh and unique flavor I haven’t seen before.

The Case Closed manga series, which is called Detective Conan in Japan, is possibly the longest-running murder mystery series in the world. It has over 1,000 chapters, all short murder mysteries lasting 2-5 chapters. While they’re not honkaku mysteries with fair play that the reader can solve, they are interesting and creative. 

The art style can appear quite “kiddie,” but don’t be fooled—murder mystery fans can find plenty to enjoy here, as it’s clear that the creator is very widely read in detective fiction. It also involves a teenage sleuth shrunk to the size of a small child by a mysterious drug, so while the characters remain static, it has some background intrigue, too.
