Everyone thinks the killer is Jeffrey.
They're all wrong.
A brutal murder shocks a quiet town, and the evidence seems to point toward one obvious suspect. The case appears solved-until the facts begin to contradict everything investigators thought they knew.
Your mission is to uncover the truth.
Study every clue, examine the crime scene evidence, compare witness statements, and use pure logic to eliminate suspects one by one until only the real killer remains.
This interactive detective puzzle delivers a fair-play mystery where every answer can be found inside the book-no guessing, no hidden information, and no outside research required.
Perfect for readers who enjoy classic detective fiction, serial killer investigations, crime scene analysis, and challenging logic puzzles.
Inside You'll Discover- 3,000 possible suspects
- 18 carefully constructed logic clues
- Crime scene evidence to examine
- Detective-style elimination challenges
- Fair-play deduction with one unique solution
- Hours of immersive mystery solving
If you enjoy detective stories, armchair investigations, serial killer mysteries, and solving impossible crimes through logic alone, this puzzle was created for you.
Can you uncover the truth before the final clue reveals the killer?
