Three suspects—Adam, Baker, and Clark—were questioned about a warehouse break-in. Adam said, 'Baker did it.' Baker said, 'Clark is innocent.' Clark said, 'Adam is lying.' If only one statement among the three is true, who committed the crime?
Baker.
If Baker did it: Adam's statement ('Baker did it') is true. Baker's statement ('Clark is innocent') is true (since Baker did it). Clark's statement ('Adam is lying') is false (since Adam told the truth). That would mean two statements are true, which violates the puzzle rule. Let's re-evaluate: If Clark did it: Adam is false. Baker is false (Clark is not innocent). Clark is false. Wait. Let's test Clark: Adam says Baker (false). Baker says Clark is innocent (false, because Clark did it). Clark says Adam is lying (true, because Adam said Baker did it, which is false). That gives exactly one true statement (Clark's). Thus, Clark did it.
