Title: The president vanishes
First published: 1934
Description: The president of the United States goes missing just as he is about to face an important vote in Congress on whether the USA should join in a world war that is in progress (this was written in 1934). The main suspects seem to be the Grey Shirts, a Nazi-style organization that threatens American stability, but there are plenty of other theories and seemingly no leads.
Places: Washington, D. C.
Time periods: 1930s
