It was an explosion that reverberated across the countryand into the very heart of early-twentieth-century America. On the morning of October 1, 1910, the walls of the Los Angeles Times Building buckled as a thunderous detonation sent men, machinery, and mortar rocketing into the night air. When at last the wreckage had been sifted and the hospital triage units consulted, twenty-one people were declared dead and dozens more injured. But as it turned out, this was just a prelude to the devastation that was to come.
