Cole delves deep into the chilling corridors of biological and chemical weapons, unraveling the threads of history, science, and geopolitical intrigue that weave the fabric of this deadly tapestry. With meticulous research and compelling prose, Cole escorts readers through the dark past and uncertain future of warfare's most insidious tools. From the trenches of World War I to the modern laboratories where these agents of death are refined and tested, Cole exposes the grim reality of a threat that remains as invisible as it is inevitable.
