A hold up in a Glasgow post office: A well dressed dotting grandfather hands his beloved grandson to a tattooed stranger, steps out of the queue and helps the robber. He seems to know that the man can't leave the post office and let him live. He stands, passive, and lets the man do what he wants.

Morrow begins the investigation with a bad feeling about it. She wants to go home. That's all she ever wants to do, to go home to her boys, but the robbery pulls her into the city and lives she could only begin to imagine.
