On April 3, 1956, according to news reports, a Mrs. Julia Chase of Hagerstown, Maryland, while on a tour of the White House, slipped away from her tour group and vanished into the heart of the building. For four and a half hours, Mrs. Chase, who was described later as dishevelled, vague and not quite lucid, wandered through the White House, setting small fires—five in all. That's how tight security was in those days: a not-quite-lucid woman was able to roam unnoticed through the executive mansion for more than half a working day.
