About five minutes, best done on the phone with the grandparent. Your answers personalize all twelve letters — no two detectives get exactly the same case.

Part 1

The Detective

The kid receiving the letters. We only ever ask for a first name — never anything more.

Part 2

The Witness

The grandparent — Witness G, a character in the mystery. These ten memories get woven into the case itself.

Part 3

The Logistics

Where the letters go, and where the monthly grandparent briefing goes.

Payment is handled separately via our secure checkout link. Your detective’s spot is reserved as soon as you enroll.
