What you’re actually buying
Not a PDF library. An unfinished story, and the question becomes what happens next.
The digital envelope
Every five days you receive a letter from a character inside the investigation, about two pages, plus printable extras: a map tile, a collectible plate, a clipping, a verdict card. Print what you want. Keep the rest on screen.
The Two-Lock ending
Letters 1–5 plant everything a sharp reader needs for who and how. The decisive why and final proof surface only in letter 6. Drip every five days, or unlock all six at once.
Q4 case lineup
Four registers. Same six-letter mechanic. Pick the flavor that fits how you like to read.
