CASE ZERO
Case 206

Who is guilty?

Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.

Amira: “Neither Amira nor Hugo is guilty.”
Jack: “The guilty person is either Tess or Hugo.”
Tess: “Mae is innocent.”
Hugo: “The guilty person is either Jack or Hugo.”
Mae: “Hugo is innocent.”
Random case
Solution: Jack 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.
