Case overview

Anna Okafor brings a box of family keepsakes to the kitchen table on a rainy Saturday, planning a quiet afternoon with her nephew Theo. They laugh over the box's old labels until Anna tries to lift one glossy layer and finds that it will not come apart cleanly from the next. Only some of the layers have changed. Theo remembers moving the box once, but neither of them can remember where it spent the rest of the year. Anna does not want to make the problem worse by guessing. She starts a list: which pieces changed, what touched what, when the box was last opened, and whether another group shows the same problem. The case begins with a family memory, an old box, and a small physical mystery that will only make sense once the ordinary history is put in order.
