We've got a fresh case for you, now that you've proven yourself - a classic (Sudoku) locked room mystery. We can't figure out the killer's trick, but we don't need to - the statements from the Witnesses don't add up, so you just need to figure out their lies instead.

Truth and Lies: Witnesses (represented by regions) that have Clues are either Truthful or Lying. The descriptions for Clues below describe how those Clues work within Truthful regions. Lying witnesses, however, disobey the rules for Clues - "must" becomes "must not", and vice versa. Clues cannot be on or cross the border between a Truthful and a Lying region.

In this case, we have 5 Witnesses, and either 2 or 3 of them are Lying - you'll have to figure out the exact number for yourself. The rest of the Witnesses are Truthful, while the 6th region represents a Security Camera.

Secruity Cameras: These wonderful devices don't count as Truthful or Lying, because the only Clues they provide within their region are given digits. They can sometimes be misleading, though - Cameras can have Clues on their border with Truthful or Lying regions, and that Clue counts as being part of the other region (and thus can either be true or a lie.)

Keyholes: Cells seperated by a white keyhole must contain consecutive digits.

Locked Doors: A cell on a black keyhole must NOT contain digits in a 1:2 ratio.

Lifelines: Each pair of adjacent digits on a green line must have a difference of 3 or more.
