CASE ZERO
Case 010

Who is guilty?

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

Ava: “The guilty person is either Miles or Zoe.”
Eli: “Nora is innocent.”
Nora: “The guilty person is one of Eli, Miles or Zoe.”
Miles: “Nora is guilty.”
Zoe: “Miles is guilty.”
Random case
Solution: Miles 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.
