Four Levels. One Unbroken Equation.
Every chapter in The Fourth Clue deepens the investigation. Deduce mathematical anomalies, cross-reference suspect alibis, and unlock the truth.
The Midnight Conservatory
Lord Harrington was poisoned in the glass botanical pavilion during the lunar eclipse. The mechanical irrigation clock was sabotaged to run on an irregular 12-hour modulus, freezing four discrete greenhouse valves.
Key Suspect Files
2 Persons of InterestDr. Evelyn Vane
Resident Botanist
Motive: Lord Harrington threatened to confiscate her rare hybrid belladonna specimen.
Alibi: Claims she was recalibrating the botanical timer in the basement from 23:00 to 00:30.
Arthur Finch
Estate Groundskeeper
Motive: Faced imminent termination over unaccounted chemical stocks.
Alibi: Reported fixing the exterior perimeter gate; no witness corroboration.
Investigator Field Briefing
Determine the discrete congruent timestamp that overrides the automated poison ventilation seal before dawn.
All four clues synthesize into a singular mathematical key that unmasks the true identity of the perpetrator.
