Each case in this manga is a stand alone mystery, and we are still fairly early in the series. So while reading in order will be better to understand the recurring characters, it’s not necessary to enjoy the individual stories.
Hajime Kindaichi is tricked into qualifying for a treasure hunt on an isolated island, thinking his family is in financial trouble. The reward soon becomes the furthest thing from his mind when the fortune seekers find themselves trapped on the island with a murderer.
The Kindaichi Case Files manga continues to be somewhat formulaic in that each case is set up in classical mystery style. We get some set up, meet potential victims/suspects, something bad happens and away we go. The fun with this series is the way pieces of the story combine and the fact that Kindaichi’s adventures are always pretty distinct, interesting, and clever. Treasure Isle gives us a particularly weird cast of characters with diverse reactions to what’s happening. This mystery felt different than the others, which is always nice in a genre where things can get repetitive. I really liked the twists in this one and the way it all came together. As always while some plot details will remain obscured until spelled out there are clues throughout and the main mystery is solvable.
One of the best volumes yet. Highly recommended.
