wouldn't you know it. One of my favourite little novels, Paul Coelhos, the Alchemist was set here in Tarifa. Santiago, a young shepherd boy, the central character in this delightful story, is disillusioned with life and sets off to find treasure!! He wanders across much of Africa and from memory gets as far as Egypt. No treasure, he does meet interesting people along the way and almost falls in love with a beautiful young girl, Fatima, but something doesn't quite ring true for him so he heads back home to Tarifa and there in the churchyard ruins, where he began his journey he meets the love of his life!!
So my moustache theory is that what ever you are looking for, it is there, generally right under your nose!! Booboom!
