Teacher

Who Killed the Teacher?
45,000 suspects. 17 clues. One killer hiding in plain sight.

A teacher is dead. Found in the hotel lobby just hours before the keynote address. And somewhere among 45,000 educators, guests, and conference attendees, one killer is hiding.

Are you ready to solve the case?

17 Clues

Every clue matters.

The mystery begins with 17 clues. At first, they may seem simple, but each one is part of a much larger puzzle. Some clues help you eliminate names quickly. Others ask you to look closer, compare pages, notice patterns, and connect details across the book.

No clue is random. No detail is wasted.

45,000 Suspects

This is what makes the investigation feel so big. You are not choosing between ten suspects in a neat little lineup. 

The book is designed for slow, satisfying elimination. You will scan pages, compare names, check clue conditions, mark possible suspects, and return to earlier pages when a new clue changes what you thought you knew.

The Challenge

The rules are simple.

 

Read the clues.
Search the names.
Eliminate the suspects who do not fit.
Keep going until only one name remains.

 

But simple does not mean easy.
