Case 054
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Amira: “Neither Amira nor Mae is guilty.”
Jack: “The guilty person is either Tess or Hugo.”
Tess: “The guilty person is one of Tess, Hugo or Mae.”
Hugo: “Neither Hugo nor Mae is guilty.”
Mae: “None of Amira, Tess or Mae is guilty.”
Random case Solution: Hugo 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.
