Across Europe on May 8, VE Day was celebrated to mark the end of World War 2.

This reminded Mario of an email / phone call he received a few years ago from a guy called Fin Dwyer .

Fin is a historian and presenter of the hugely popular Irish History podcast.

He had been working on a fascinating story about a time after the war, when a number of leading Nazis – people who Donald Trump would have called ‘Bad Dudes’ -  were welcomed in Ireland and given shelter here.

One of them was a particularly nasty character called Otto Skorzeny, one of Hitler's right hand men.

But what came as a complete surprise to Mario was that Fin told him how his Grandfather – who by then had been living in Ireland for years – mounted a campaign to make Irish people and officials aware of just how nasty this guy Otto was, and why he should be expelled from the country.
