The locked office
A manager leaves a locked office at 6 p.m. The next morning, a report is on the desk even though the lock log shows no entry. The report was not there when the manager left. How is that possible?
Lateral challenge at medium difficulty.
Hint
A locked door restricts people, not every way an object can move.
Answer and method
The report could have been delivered through an internal document slot, printed remotely by a printer inside the office, or placed by someone already inside before the manager checked. The facts do not identify one answer, so a good investigation tests these channels rather than declaring a culprit.
Reusable reasoning moveIn real investigations, list multiple explanations and seek discriminating evidence.
