I want to know the answer to the following question:
Where is the "Tardy Book" kept?
All the background I'm provided with is that "A boy who is late for any division or other appointment may be required to sign "Tardy Book", a register kept in the School Office, between 7.35am and 7.45am, every morning for the duration of his sentence (typically three days).". Is that enough to answer the question?
