Puzzle Pack #2 Puzzle 38 Answer

Aaron’s clue directly says that Flora is one of Katie’s six criminal neighbors. That identifies Flora as criminal immediately. So Flora must be criminal.

Flora’s clue says that Hilda is one of Olof’s 4 criminal neighbors. That directly identifies Hilda as a criminal. So Hilda must be criminal.

Flora’s clue says Olof has exactly 4 criminal neighbors, so among Olof’s 5 neighbors there is exactly 1 innocent. In the current state, that one innocent must be among the four still-unknown neighbors D2 Isaac, C3 Noah, C4 Tina, and D4 Uma. But from the facts already established for this step, the only people in that group who can still be that innocent are D2 Isaac, C4 Tina, and D4 Uma. So C3 Noah cannot be the innocent person there, and Noah must be criminal.

Among Olof's neighbors, there is exactly 1 innocent in total. The row 4 neighbors of Olof are Tina and Uma, and that smaller group already contains exactly 1 innocent. That means the full set of Olof's neighbors has already used up its only allowed innocent within Tina and Uma. The only other still-unknown neighbor outside that smaller group is Isaac, so Isaac cannot be innocent. So Isaac must be criminal.
