In the story a Catholic man, while discussing religion with the agnostic narrator, recounts his youth as an altar boy when the village atheist, a baker named Blacker, tried to bribe his ten-year-old self into providing a consecrated Host.
Greene captures in his art the qualities, or lack thereof, possessed by the vehement atheist. See his familiar-sounding description of Blacker:
"There was much more hate than love, poor man, in his make-up. Can you hate something you don't believe in? And yet he called himself a free-thinker. What an impossible paradox, to be free and to be so obsessed."
Even Blacker's words prefigure Myers' own:
"'What's the fuss? It's only a bit of bread' [Blacker said,] looking so longingly and pleadingly up at me that even as a child I wondered whether he could really think that, and yet desire it so much."
