By nightfall, Mark had set up the silent trackers. Lena stayed late, watching the live feed of access points on her laptop. Emilia had gone home, and Elias was working in his office down the hall.
As the hours ticked by, Lena's eyelids grew heavy. She was about to shut her laptop when a notification popped up, a badge swipe at the archives.
Her breath hitched. The timestamp showed the entry was just minutes ago.
Lena grabbed her phone and dialed Elias.
"Someone's in the archives right now." Lena said.
"I'll meet you there," Elias replied.

Lena and Elias approached the archives cautiously, their footsteps muffled on the carpeted floor. The door was slightly ajar, and the faint hum of a computer echoed from inside.
