For staff: the last Monday drop, two minutes to set up.

Before the children arrive. Wrap the missing object from week one in a blanket or towel and leave it somewhere new, like a shelf or a box. Put the printed log page on top of it. Put the object's spot back as it was, empty, for the children to fill.

The sealed printable. Print the log page: "Club bell. In for a crack, 3:48, signed by the caretaker. Mended, signed by the mender. Out, today 5:15." Leave a blank line for the room to sign.

The episode. Read the story aloud, or play the recording. About five minutes.

Jobs by age. The youngest count the hands in the log. The middle group checks 3:48 against the window on the week-two timeline. The oldest decide what can now go in ink, and rub out the pencil guesses.

The answer phrase. THE BELL WAS BEING MENDED. A room that missed weeks can start here; the board shows what happened.

No printer? Write the log page by hand.

The Elders' Clue (for home). Write this on the back of the printable: Who in our family mends things? What did they mend last? Only a grown-up can answer it. Next Monday, pin their answers to the case board in pencil, under "what grown-ups remember". Nothing has to come back; the room carries on either way.

For the ride home. Ask: when did you lend something, and who wrote it down?
