A BBC mystery serial is trending toward its second season and the source shows strong fantasy hook content (family, greed, will), signaling a fan base hungry to theorize in real time — the same audience pattern that turned other dramas into social events.
I, Jack Wright is real (BBC/Chris Lang, John Simm, aired 2025, season 2 acquired by BBC) but is a niche UK murder-mystery with limited US reach; the 200+ GB Google Trends claim is plausible for a small but engaged fanbase, not a blockbuster.I, Jack Wright - Wikipedia ↗BBC acquires I, Jack Wright season 2 - The Killing Times ↗
TV Time (15-year incumbent second-screen app) is shutting down July 15, 2026, opening a real gap; however Reddit/Discord/Goodbye free theory threads already serve whodunit fans, and no paid whodunit-specific companion exists — only Clue (board game) Companion.TV Time Is Shutting Down (July 15, 2026) ↗TV Time is shutting down alternatives - AlternativeTo ↗
Mystery superfans rarely pay for theory trackers; surviving alternatives (Showly, Simkl, SeriesGuide, Serializd) are all free, and the Clue Companion app is free.

Product is fundamentally tied to one 6-episode BBC serial with multi-year gaps between seasons; once the season ends engagement collapses and the next mystery (e.g., a different Lang show) would need fresh content; no show-agnostic engine described.I, Jack Wright - Wikipedia ↗
Spoiler walls, clue cards, and suspect rankings are all straightforward web/mobile features with no licensing required; main work is content authoring per episode, which scales poorly across shows.The Second Screen Phenomenon | MovieRec ↗
