👀 SPOILER-FREE SUMMARY

Conan and Heiji Hattori are deep in the trenches of a multi-part poisoning case, and this middle chapter is where the real detective work kicks in. Expect a methodical, tension-laced episode that rewards attentive viewers — clues are layered carefully, and the pacing gives you room to play armchair detective alongside the protagonists. The Wakamatsu family case proves to be no straightforward affair, demanding both Conan's and Heiji's full analytical firepower. Kazuha and Ran remain present, grounding the intensity with familiar character dynamics. The tone stays firmly in suspense territory without rushing toward answers. This is classic Case Closed at its most cerebral — a slow-burn investigation episode designed for fans who love dissecting evidence and watching deductions unfold piece by piece before the final reveal.
