re: #195 The Ghost of the Beardsman

Given that Hitler was part of a movement, and his ideas were not 100% original, simplest danger of time travel would be killing Hitler, resulting in “more competent Hitler.”

Like Martin Bormann.

There’s a SF story where someone goes back in time and *does* assassinate Hitler. So the Nazi Party has to bring out and use his double, who also happens to be a little bit unstable.
