The Missing Minute
Every minute has an alibi. Except one.
Your role
Evidence is a system. Read it like one.
Reconcile cameras, badges, calls and travel times to find the only person who could enter the unrecorded minute.
First-case tutorial
What you actually do
- Treat the briefing as context only. Every elimination must still be proven by a formal record.
- Use the last and next verified records.
- Allow the minimum travel time on both sides of the missing minute.
- Eliminate anyone without archive access.
Formal rules
- A person cannot travel faster than the listed minimum.
- Both arrival and departure must fit inside the unverified interval.
Cases in this family rotate through multiple reasoning archetypes, so higher difficulty changes the deduction structure rather than simply adding more rows.
