I first met Jose Luis Vercas on the concrete apron jutting out into the mouth of the Targus where the splendour of the Manueline Port of Lisboa ends and a wide expanse of river divides the city from Alcântara. He was short, but well-muscled and possessed of that curiously Portuguese combination of a mane of swept-back, black and wavy hair; and a forehead so high it begged to be labelled, “domed”. He said he too was a teacher, but offered no hint of subject or at what level he taught and, to be frank, my interest did not extend that far.

“Do you have it?” I asked in my formal Portuguese. He smiled and nodded – a slight movement of his head, causing a lock of stray hair to struggle free. Patting his messenger bag, he said in accent-free English, “It’s here.”
