That evening in early summer, as I walked back through the somber, treacherous twilight of Barcelona, I could not blot out Clara's story about her father's disappearance. In my world death was like a nameless and incomprehensible hand, a door-to-door salesman who took away mothers, beggars, or ninety-year old neighbours, like a hellish lottery. But I couldn't absorb the idea that death could actually walk by my side, with a human face and a heart that was poisoned with hatred, that death could be dressed in a uniform or a raincoat, queue up at a cinema, laugh in bars, or take his children out for a walk in the morning, and then, in the afternoon, make someone disappear in the dungeons of Montjuic Castle or in the common grave with no name or ceremony.
