One of the decorative lighthouse blueprints hanging on the wall sits slightly crooked. Behind it, a faint outline where something else used to be pinned catches your eye.

WHERE DO YOU GO FROM HERE?

Do you…

• Ask the Environmental Regulator if they removed any documents earlier?

• Lift the blueprint and check behind it — something may have been hidden there?

• Ask the Rival Developer if they moved the blueprint to compare designs?

Follow the trail… if you are brave enough.
