The book does not contain the solution. This page does not either — until you tell it a name.

Checked locally in your browser. Never sent anywhere, never stored, never in the page source.
Apply the wide clues first — the ones that eliminate large groups at once, before the clues that require checking individual names closely.
Work through the register systematically, floor by floor. Don't jump around — it's easy to miss a name if you skip sections.
Keep a record as you go. Cross out eliminated names clearly. When you're down to a handful, re-check each one against every clue from the start.
Cut out the clues page if it helps — keep it beside the register as you work.
Don't rush the final clues. The last few are the most precise.
Does the book include the solution? No. The solution is not in the book. Use this page to verify your answer once you have one.
What if I think I've found more than one name that passes every clue? This should not happen — exactly one name passes every clue. Recheck each clue carefully against both names.
I've been through the whole register and no name passes every clue. What do I do? Recheck clues in order, starting from the first. It's easy to misapply an early clue and carry that mistake forward.
