Puzzle Pack #1 Puzzle 40 Answer

Jane is at A3 and Martin is at D3, so the people in between them are Karen at B3 and Larry at C3. Larry’s clue says there is only one innocent in between Jane and Martin. Since Larry himself at C3 is already known to be innocent, that uses up the only innocent between them. Therefore, we can determine that B3 is CRIMINAL.

The people above Nick at A4 are Alex at A1, Freya at A2, and Jane at A3, and the clue says exactly 2 of those 3 are criminals. Freya’s neighbors are Alex, Betty, Gary, Jane, Karen, Nick, and Olof, so among the three people above Nick, Freya is neighbors with Alex and Jane, but not with herself. Since exactly 1 of the 2 criminals above Nick is Freya’s neighbor, Freya cannot be innocent, because then the two criminals above Nick would have to be Alex and Jane, and both of those are Freya’s neighbors. Therefore, we can determine that A2 is CRIMINAL.

Nick is at A4, so his neighbors are A3, B3, B4, A5, and B5. We already know B3, Karen, is a criminal, and Freya’s clue says that of Nick’s two criminal neighbors, only one is in column B. Among Nick’s neighbors, the people in column B are B3, B4, and B5. Since B3 is already one of Nick’s criminal neighbors and the clue says only one of Nick’s two criminal neighbors is in column B, B4 and B5 cannot be criminals. Therefore, we can determine that B4 is INNOCENT and B5 is INNOCENT.

Freya’s clue says Nick has exactly 2 criminal neighbors, and exactly 1 of those 2 is in column B. Nick’s neighbors are Jane at A3, Olof at B4, Vince at A5, and Wanda at B5; among the column B neighbors, Olof and Wanda are both already known innocents, so Nick cannot have any criminal neighbor in column B. That means the number of Nick’s criminal neighbors is actually 0, not 2, unless Nick himself is not one of the people the clue is describing as having two criminal neighbors. Therefore, we can determine that A4 is INNOCENT.
