What this episode contributes

A distinct chapter, not a recolored board list.

The exposure profile, freezer barcode trail, and altered lab logs say the contamination story was engineered. Its setting and narrative language help establish the five-part series, while the underlying board route maintains a clear puzzle grammar: scene intake, first contradictions, forensic pattern, suspect pressure, motive and method, then final reconstruction.

    Start with the visible version of the fictional event.

  2. 02Pattern pressure

    Use recovered fragments to make the surface explanation less convincing.

  3. 03Final reconstruction

    Reserve the final picture for players who complete the episode inside the product.
