Al Capone and GKC

The following anecdote from Chesterton's trip to Italy is quite interesting (and which I have mentioned before, but found a new source confirming it):

While Dorothy Collins [GKC's secretary] had been taking Chesterton's dictation or Gilbert was visiting or lecturing, Frances [GKC's wife] was sometimes at a loose end. Fortunately, a fellow guest in the hotel, a pleasant American gentleman with a very large Packard limousine and his own chauffeur, was happy to put his car at Frances' disposal when it was not needed by himself. Gilbert would no doubt have been delighted in the chauffeur's name, Dominic Cinderella, but it would have been interesting to have been able to note his reaction when some time later, after may kindnesses by the American, Frances introduced nice Mr. Capone to Gilbert: Alphone Capone was perhaps enjoying a quiet holiday after all the excitement of the previous February's St Valentine's Day massacre.
