A MURDER MYSTERY LOGIC PUZZLE
Part of One Killer Mysteries

Agnes Whitlock, Head Housekeeper of the Continental for twenty-nine years, was found at the foot of the service stair during the hotel's Golden Jubilee week. Alistair Renshaw, Head Concierge, has written seventeen clues — each one true of the person who killed her, true of no one else in the Register.

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

HAVE YOU FOUND THE KILLER?

Checked locally in your browser. Never sent anywhere, never stored, never in the page source.

THAT NAME IS NOT THE KILLER.
Go back through the seventeen clues. Check your surviving name against each one again — somewhere, one of them eliminates it.
Enter a name from the Register.

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.

Does Y count as a vowel?
No. For any clue involving vowels and consonants, only A, E, I, O, and U are vowels. Y is always a consonant.

Are there any hyphenated names or middle names in the Register?
No. Every entry has exactly one first name and one last name. There are no hyphens, middle names, or titles.

For clues about the room "directly above" or "directly below" — do I look across floors?
Yes. The Register is one continuous list by floor. Directly below means the next room in sequence, even if it's the first room on the floor beneath.

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.
