G. K. Chesterton: The Wisdom of Father Brown

6. The Head of Caesar (continued)

"Then it rushed over me that I was being blackmailed for the theft of the bronze piece; and all my merely superstitious fears and doubts were swallowed up in one overpowering, practical question. How could he have found out? I had stolen the thing suddenly and on impulse; I was certainly alone; for I always made sure of being unobserved when I slipped out to see Philip in this way. I had not, to all appearance, been followed in the street; and if I had, they could not `X-ray' the coin in my closed hand. The man standing on the sand-hills could no more have seen what I gave Philip than shoot a fly in one eye, like the man in the fairy-tale.

"`Philip,' I cried helplessly, `ask this man what he wants.'

"When Philip lifted his head at last from mending his net he looked rather red, as if sulky or ashamed; but it may have been only the exertion of stooping and the red evening light; I may have only had another of the morbid fancies that seemed to be dancing about me. He merely said gruffly to the man: `You clear out of this.' And, motioning me to follow, set off wading shoreward without paying further attention to him. He stepped on to a stone breakwater that ran out from among the roots of the sand-hills, and so struck homeward, perhaps thinking our incubus would find it less easy to walk on such rough stones, green and slippery with seaweed, than we, who were young and used to it. But my persecutor walked as daintily as he talked; and he still followed me, picking his way and picking his phrases. I heard his delicate, detestable voice appealing to me over my shoulder, until at last, when we had crested the sand-hills, Philip's patience (which was by no means so conspicuous on most occasions) seemed to snap. He turned suddenly, saying, `Go back. I can't talk to you now.' And as the man hovered and opened his mouth, Philip struck him a buffet on it that sent him flying from the top of the tallest sand-hill to the bottom. I saw him crawling out below, covered with sand.
