Clues do not have to be solved in order.

Start with clues that remove full rows or pages first.

Keep notes on names, rows, seats, and identifiers.

Exact spelling matters.

Use the answer key only for final validation.

For The Passenger in 14B, compare all five grids before locking your final suspect.

For The Killer Never Logged Out, the shared gateway is the strongest proof.
