The Harrington Notation

A quiet evening at Harrington House is disrupted when a series of cryptic notes begins to surface in places no one expected. At first, the fragments seem unrelated: a date, a missing page, a name that should not appear at all. The deeper you look, the clearer it becomes that the truth has been edited long before your team arrived. Contradictions multiply, timelines bend, and familiar details begin to feel staged. What looked like an intellectual puzzle starts to carry real personal risk. Every clue changes the meaning of the one before it. By the time the pattern locks in, the case is bigger than the house.
