"The Dynamite Fiend" brings to light the stunning story behind one of the most devious criminals of the nineteenth century, Alexander "Sandy" Keith. Beginning his dark career as a Confederate secret agent, Keith helped orchestrate some of the most infamous terrorist plots of the Civil War. In peacetime, dogged by creditors and victims of his frauds, Keith kept on the move, leaving more scams, schemes, and cheated women in his wake. As his situation became more desperate, his obsession with explosives and violence became more intense, leading to a horrifying plot that he put together while posing as a prosperous American businessman living in Germany. In 1875, one of Keith's bombs exploded on a dock, killing eighty people and injuring fifty more. The world heralded the deed as the "Crime of the Century" and Keith became the "Dynamite Fiend" and a true mass murderer.
