Case Closed: The Fourteenth Target
What they share
Both films are directed by Kenji Kodama, and they both carry the mindfuck, playful mood tags, and they sit in Adventure / Animation / Crime / Mystery territory. If that's the register that drew you to Detective Conan: The Time Bombed Skyscraper, the second film will land in a comparable space — through a different lens.

What Case Closed: The Fourteenth Target is
Monte Carlo, spring. A dropped wine glass. Professional gamblers are targeted in escalating attacks. Mouri Kogoro is the next named victim, so Conan must race against time to uncover the connections. A highlight of the late-1990s Case Closed run.
