🔍 HOW IT WORKS

Read a clue. Cross out every creature it rules out. Keep going until one is left standing.

That one is your killer.

You mark up the page directly, like a paperback you can never ruin:

• Cross out names in colour
• Fade names away to clear a page
• Underline and highlight, 4 colours
• Circle or box anything
• Pin a clue so it follows you
• Bookmark pages with colour tabs
• Notepad for counts and theories
• Rule out whole chapters at once
• Undo anything, as often as you like
• Check your answer instantly

Progress saves itself. Reset any time for a completely clean run.

No search. No find-on-page. No auto-counting. The deduction stays yours.

📖 THE CASE

The Keeper of the Creatures keeps an unusual ledger — familiar animals, forgotten beasts, legendary monsters, gods and ghosts.

It doesn't only list them. It holds them.

So there is one rule above all: never tear out a page.

Today, somebody did.

Some poor creature has been undone at the hand of an unknown assailant.

The Koala was found standing over the wrecked ledger, swearing it wasn't him. Before he ran off, he pressed 18 clues into the Keeper's hands to prove it.

🎯 WHY THIS ONE IS DIFFERENT
