When someone goes missing, the first thing an investigator asks for is their diary. One week of it tells the players who they saw, where they went and which appointment they never came back from.
The page is one week on A5: the year and the week at the top, a box for each day from Monday to Sunday with its date, and a box for notes. Each new line in a day is a new appointment. A circled date, a struck-out meeting or a note in someone else’s hand is a handwritten mark on top of the page, so the week can look used.
Four books: a present-day weekly planner with a storage unit nobody rented, a Miskatonic professor’s 1926 diary whose last week ends in Kingsport, a village almanac of feasts and moons with the Dark Moon falling twice, and a space station’s duty roster that keeps putting a dead man on shift. A5 at 300 DPI. The letter found folded in its back cover is a Message.
