An antique pocket watch was stolen from a locked display case. Three employees had keys: the manager, the clerk, and the janitor. The manager said he was updating payroll. The clerk said she was sweeping the back aisle. The janitor said he was scrubbing the second-floor windows. Detective Gray arrested the clerk. Why?
The clerk said she was sweeping the back aisle, but sweepers don't use keys.
The clerk claimed she was sweeping the back aisle, but the display case required a physical key to unlock, and her job description as a clerk didn't involve sweeping—wait, the clerk claimed she was sweeping, but the display case was glass and she left muddy footprints near it.
