How does a seemingly ordinary boy prove to be so extraordinary that he’s given a halo by the Catholic Church? Saint Carlo Acutis was just 15 years old when he died in 2006. William Crawley travels through Italy to the places most associated with the young Carlo to discover for himself what set this teenager apart from the rest.

In Assisi, William meets Carlo’s mother Antonia Salzano Acutis who reveals how her son showed an unusual generosity for a teenager. He visits Carlo’s tomb, where Domenico Sorrentino, Bishop of Assisi, explains the connection between St. Francis and Carlo, as a bridge from the past to the present. At Carlo’s old school in Milan, Istituto Leone XIII, his former professor, Fabrizio Zaggia, recalls his curious mind. And contemporary students talk of how they can relate to the Saint who designed websites.

But is it all too convenient for the Catholic Church in this Jubilee Year to find a saint that appeals to this younger generation? William ponders this in Rome with John Allen, editor of Crux, the online Catholic newspaper, before heading off to St Peter’s Square and the Dicastery for the Causes of Saints where Monsignor Alberto Royo explains the investigation into Carlo’s life to see if it was one of ‘heroic virtue’.
