This webpage of Find a Grave offers viewers a few photos of Benét's grave, plus a brief but informative bio by "Iola" that tells me a few things I didn't know, including this:

A short story collection, 'Thirteen O'clock' published in 1937, included . . . one of his most famous stories, 'The Devil and Daniel Webster'. The story was later made into a play, an opera, and a film, the title becoming 'All That Money Can [Buy].'

Also, this information speaks to Benét's 'Americanism':

By 1940, Benét was a strong advocate of America's entry into WWII.

But the question is "Why?" For Europe's sake? Or America's?
