CASE ZERO
Case 086

Who is guilty?

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

Amira: “The guilty person is either Amira or Jack.”
Jack: “None of Jack, Hugo or Mae is guilty.”
Tess: “Jack is guilty.”
Hugo: “Hugo is innocent.”
Mae: “The guilty person is either Jack or Tess.”
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.
