Fermín is a character who has done time as a tramp, and perhaps because of the hunger he’s suffered, he has an insatiable appetite for chocolate. Living in Switzerland, I can testify as to the reality of its ‘impossibly blue lakes’ and ‘Technicolor green fields’.
‘As a way of repaying Fermín for his infinite patience, Tomás brought him boxes of Swiss chocolates stamped with photographs of impossibly blue lakes, cows parading along Technicolor-green fields and camera-ready cuckoo clocks.’
