Chapter 1One minute late

Clockwork City ran on gears: gears in the bridges, gears in the trains and, at its heart, the enormous gears of the great clock.
Amir had been the clockmaker’s apprentice for exactly one week when Master Ottilie came down to breakfast looking worried.
“The great clock is losing time,” she said, stirring her tea without drinking it. “One minute every single day, never more and never less.”
One minute did not sound like much. But after a week, the morning train was seven minutes late, the bakers’ bread was overdone and the airships were missing their moorings.
“I’ve checked every gear,” Master Ottilie sighed. “Fresh eyes might see what mine can’t. Where would you start?”
What happens next is up to your child
Where should Amir begin the investigation?
Questions for grown-ups to ask
Did you spot it?
- EasyHow much time did the great clock lose each day?Answer: Exactly one minute.
- MediumWhy did a small delay cause big problems?Answer: It added up: after a week the trains were seven minutes late, the bread was overdone and the airships missed their moorings.
- HarderIn “Too light”, why did the lighter weight slow the clock even though weight doesn’t matter much?Answer: It was fixed lower down, making the pendulum longer, and a longer pendulum swings more slowly.
Talk about it
- Which clue did you follow? Could more than one cause have been true at the same time?
- Master Ottilie says fresh eyes might see what hers can’t. When has someone new helped you notice something?

Reading it together
The Clockmaker’s Apprentice is written at Litsee’s reading level for age 9. Each path finds a different, real cause of a slow clock (a weight on the pendulum, heat making metal longer, the pendulum’s length, the tower moving), so the endings reward careful thinking.
Each part of the story has a real fact card about British inventors and railways from the Litsee app’s fact bank, with its source. Ada Lovelace and Tim Berners-Lee are good names to look up together afterwards.
Make a pendulum from string and a small weight and time ten swings. Then make the string longer and time it again. Your child will see for themselves why the length matters.
