Inside are about two dozen glossy, letter-sized photographs. They start off innocently, scenes around Scotland that may be rather vague. As Joe flips further through the stack it's obvious they're of locations linked with his childhood home in Arran, Scotland. The village school where Joe and his sister went to. The town. His parents' house. Various locations where the Bells liked to visit all around the island. Some of the photographs are taken at the right angle so the photograph taker's shadow -- an unmistakable billowing robe associated with Death Eater regalia -- are seen on the ground.
There's a post-it note attached to the last photograph that simply reads "We know. Stay tuned."
