Midnight #4

This anthology issue contains the story "Who Knows?" in which young detective Eddie Bartlett uses a lie-detector machine to interrogate Sam Payne, a night watchman suspected of involvement in a warehouse robbery. Through careful questioning about the details of the crime—including Sam's claim that he was struck on the head during the incident—Eddie gradually reveals inconsistencies in Sam's account, ultimately proving that Sam was lying about his involvement and participation in the robbery. The story emphasizes the power of logical deduction and the lie-detector as a tool to uncover the truth in criminal investigations.
