You are a retired detective, but a string of bizarre murders shatters your peaceful life.

As you begin piecing together the clues, things start to feel increasingly wrong.

Every testimony seems truthful, yet none tells the whole story.

Can you piece together these fragments of information and uncover the secret hidden behind the cases?

This is a single-player, Sudoku-style deduction game. You won't need to rely on guesswork to solve cases; instead, organize, eliminate, and verify until every clue fits.

In each case, you will:

- Read case clues and suspects’ statements;

- Analyze relationships between people, locations, times, objects, and actions;

- Place suspects on the deduction board and gradually narrow down the possibilities;

- Piece together the hidden connection between seemingly independent cases.

Multiple victims. Multiple inexplicable crime scenes. And an unseen thread running through them all.

Do they point to a single killer, or does someone want everyone to believe that a “serial killer” exists?

The truth lies in every possibility you rule out.
