Description
Four stories. One borrowed alibi.
A historic lens disappears during a nine-minute blackout at Alderwick Observatory. An access card points at one person. An authentic photograph seems to clear another. A machine records a perfect trace. What do these records actually prove?
Explore twenty evidence files, investigate four suspects and establish six connected findings. Search the archive, compare any two records and build your own timeline. Write your deductions and cite the evidence that supports them.
