Puzzle Pack #2 Puzzle 35 Answer

Vince’s clue says there is exactly one innocent among the people who are neighbors of both Rose and Stella. That shared group is Larry, Mark, Vince, and Wanda, and Vince is already the one known innocent in it. So the other three people in that shared group cannot be innocent. That makes Larry, Mark, and Wanda criminals.

Wanda’s clue says that Isaac is one of Donna’s two innocent neighbors. That directly identifies Isaac as innocent. So Isaac must be innocent.

Donna’s neighbors are Claire, Hank, and Isaac, and Wanda’s clue says exactly 2 of those neighbors are innocent. Since Isaac is already innocent, Claire and Hank together contain exactly 1 innocent. Isaac says he has exactly 3 innocent neighbors, and among his neighbors the unknown people are Claire, Donna, Hank, and Oscar, with Mark already criminal. Claire and Hank account for only 1 innocent, so the remaining 2 innocent neighbors Isaac still needs must be Donna and Oscar. So Donna and Oscar must be innocent.

Oscar’s clue directly says that Katie is one of the exactly 2 criminals above Peter. Since the clue explicitly includes Katie among those criminals, Katie must be criminal.
