He traded his pen for a microphone — and his freedom for a cell.

This is the story of Robert Henry Best, the American journalist who defected to Nazi Germany and became “Mr. Guess Who,” one of Hitler’s English-speaking propagandists.
He believed he was telling the truth. Instead, he became the vice of treason.

Captured by Allied troops in 1945, Best was convicted of twelve counts of treason and sentenced to life in prison at Leavenworth.
His broadcasts were delusional — rants dressed up as patriotism.
He died in federal custody in 1952, alone and forgotten.
