Case 198
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Amira: “Mae is innocent.”
Jack: “Amira is innocent.”
Tess: “The guilty person is one of Amira, Jack or Hugo.”
Hugo: “The guilty person is one of Jack, Tess or Hugo.”
Mae: “None of Amira, Jack or Hugo is guilty.”
Random case Solution: Tess is guilty. Testing each possible culprit leaves this as the only assignment where the culprit's statement is false and all four innocent statements are true.
