The Hissing of Summer Sands

“The whistle man” was a typical character of the portuguese sea-side during the Fascist Portugal. His story has so many versions that he has become a myth: A poor crazy man who lost his baby girl, a professional homeless who lived from the charity of rich families, a pedofile or a summer father Christmas. His whistle announced his arrival and attracted boys and girls or made them run away. Last year I found 30 seconds of footage of this man which until then was just a memory. Is he more real now?
