I find that with a lot of detective genre media (Detective Conan, Sherlock Holmes, etc), the mysteries often involve "knowledge tricks" (tricks that require prior knowledge such as match, forensics, physics, chemistry, etc.) for you to be able to figure out who the killer is.

This show does not use that type of cheap gimmick for the mysteries. The mysteries are very much grounded in logic. You don't need fantastic knowledge or a great memory to figure out the killer. I found myself making guesses based on the hints revealed throughout each case and figured out the killer before the main character explicitly pointed it out. It's an incredibly fulfilling feeling to know that you can pick up on these hints and figure out the logic. I highly encourage anyone watching the show to try to follow along the mysteries and make your best guess as well.

Even the huge reveal by the end is actually something quite logical if you've been following along. Throughout the show from the very beginning I had my suspicions about the reveal. It doesn't make the show any less exciting even if you guess right though.

It's very short, only 25 episodes. Jump right in!
