The Killer Isn't Alice

Alice looks guilty.
The evidence is devastating.
Her access card opened the restricted gallery. Her scarf was found beside the body. Her fingerprints are on the display case. Witnesses heard her threaten the victim. Security footage appears to place her near the scene just before the murder.
Everyone thinks the case is over.
Then one clue proves Alice could not have done it.
Now the real mystery begins.
Hidden inside a damaged museum access system are 43,000 possible suspect profiles. Seventeen carefully constructed clues reveal the killers identity one piece at a time. Every clue eliminates the impossible, narrows the field, and exposes another flaw in the story everyone was too eager to believe.
But this is not a mystery where you simply wait for the detective to reveal the answer.
You are the detective.
Track the names. Test the access sectors. Question every witness. Follow the forged provenance trail. Examine what the security footage actually proves, and what it only seems to prove.
Because the most dangerous evidence in this case is not false.
It is real evidence arranged to tell the wrong story.
A curator is dead.
A priceless painting hides a secret.
Someone inside the museum has spent years manufacturing history.
And Alice may have been chosen as the perfect suspect long before the murder ever happened.
17 clues. 43,000 suspects. One killer.
Can you clear Alice, expose the contradiction, and identify the only person who could have committed the murder before the final reveal?
