In the sprawling, thousand-plus episode tapestry of Detective Conan , it’s easy for a single installment to get lost in the fog of Heiji's failed confessions, Kogoro's needle-induced naps, and the ever-present shadow of the Black Organization. But then, every so often, an episode reminds you of the series’ core strength: the locked-room mystery amplified by theatrical, almost supernatural, stakes.

Have you seen Episode 717? What was your theory about the locked-room trick before the solution was revealed?

Why not a perfect score? The episode leans heavily on a cliffhanger that feels slightly abrupt. And seasoned viewers will likely guess the “trick” behind the fire arrow’s delivery system before the reveal (hint: think about timing and metal fatigue ). But the journey is still immensely satisfying.
