Case 186
The Missing File
A signed contract file vanished from the archive.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Jordan
“Drew is guilty.”
Dakota
“Either Jordan or Drew is guilty.”
Harper
“Dakota is innocent.”
Drew
“Rowan is guilty.”
Rowan
“Jordan and Harper are both innocent.”
Who is guilty?
Solution: Drew
If Drew is guilty, Drew's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
