Chapter 3: Mirrors and Smoke

By the fourth lock, trust was beginning to fracture. The mechanism required each person to enter a private booth and answer questions about the others, their responses compared by an algorithm that penalized inconsistency. The questions were disturbingly specific. What did Tomasz whisper to Maren during the second lock? Which hand did Devonte favor when reaching for tools? How many times had Lian checked the sealed entrance since they arrived? Someone was being watched more carefully than the puzzles required, and every member of the group knew it, but none could agree on who was watching whom. Yuki emerged from her booth pale and shaken. 'It asked me things about my past that I have never told anyone,' she said. 'Whoever designed this room has access to information that goes far beyond what a background check could provide.' The fourth lock opened, but the atmosphere had shifted permanently. Devonte began working slightly apart from the group. Tomasz kept his tools closer to his body. Lian continued her silent observation, and Maren caught her reflection in the polished vault surface and wondered whether the woman staring back was the architect or the subject of the experiment. The fifth lock was mathematical, a series of equations projected onto the walls that required collaborative computation. The catch was that each person could only see a portion of the equations, and the portions overlapped in ways that made deception possible. A wrong answer from any individual would reset the entire sequence. 'We have to trust each other's numbers,' Devonte said. 'That is precisely the problem,' Tomasz replied. They solved it, but it took two hours of careful verification, each person independently confirming the others' calculations through indirect methods. When the fifth lock opened, seven hours remained on the clock. Two locks left, and the group was held together by nothing stronger than mutual necessity and the growing suspicion that the vault contained something none of them had bargained for.
