With one squeeze of a trigger, or flash of a blade, the course of history can change forever. In this series - we tell the stories of assassinations throughout history, plotting the path of the killer and victim, step by step, until they meet. We examine the fall out, following the assassination of world leaders. We reveal how cultural icons were targeted, and why. And we unpack stories which you may never have heard about before. From What's the Story Sounds - and narrated by Jonathan Guy Lewis - Crosshairs is your weekly dose of crime and history, with new episodes every Thursday.
