Manchester. DCI Rick Castle is inspecting his bees when his boss phones. A minor cannabis dealer has been reported missing. His father\'s a war hero. Rick flies to Nepal, and heads up the trail. Through villages of staring children and fluttering prayer-flags. Brilliant blue skies, and snow-capped mountains. He finds a dead body. Then a second. Nothing in this world was ever straightforward. Nothing. Finally, he puts himself in the firing line, and has a decision to make. Is it the right one? The moral one.
