Shortly before midnight on Friday, July 2, 1915, police responded to the U.S. Capitol where an explosion had just rocked the Senate wing.

But, there was plenty of carnage and, obviously, great concern about security.
The next evening, Washingtonians opened their Evening Star newspaper to find a peculiar letter under the headline, “Letter Received by the Star Thought to Have Bearing on the Explosion.” The diatribe began, “Unusual times and circumstances call for unusual means.”
