The rehearsal door

The door log lost the names but kept the exact minute of entry.

3 min100 points

The main rehearsal mask is found hidden in another dressing room. A camera shows someone carrying it there through a door with personal access control. The system saved the time, but a display fault hid the name.

Three people held passes valid during different time slots. The door did not accept early requests or allow entry after a shift ended. The schedule identifies which pass was used.

What we know for certain

One of these people entered and hid the mask without help. Each pass only worked during its assigned slot. Passes were not lent, nobody followed someone else through, and there were no open doors or alternative entrances. The clock was synchronised.

Opening these five clues does not cost points.

01The recorded minute

The only entry with the mask occurred at exactly 17:25. The log has no clock offset or relevant hidden seconds.

02Berta’s pass

It worked from 17:00 up to, but not including, 17:20. It was then automatically deactivated.

03Cesc’s pass

It worked from 17:20 up to, but not including, 17:40. It did not require another person to open the door first.

04Duna’s pass

It worked from 17:40 to 18:00. Before 17:40, the reader rejected every attempt using that pass.

05Individual entry

The recording shows a single person passing through after one pass was validated. The door then closed and the mask remained in that person’s hands.
