Case 151
The Missing Painting
A framed artwork disappeared from a private hallway.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Rowan
“Noah is innocent.”
Jordan
“Either Rowan or Lane is guilty.”
Noah
“Rowan and Reese are both innocent.”
Reese
“Jordan and Noah are both innocent.”
Lane
“Rowan is guilty.”
Who is guilty?
Solution: Lane
If Lane is guilty, Lane's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
