Synopsis

The origin of the blood – spattered on a wall in a derelict building, clinging to a rooftop railing, staining the broken glass of a high-floor window – is the puzzle Conan must unravel. He must find the answer to this unsettling question if he hopes to expose a cunning killer who has taken root within the facade of a harmless mountaineering society, a group concealing a perilous truth.
