is true that by studying magic he fell at last under the blight of black magic; the black magic of this scoundrel Strake. But my brothers were wrong about the antidote. The antidote to black magic is not brute materialism or worldly wisdom. The antidote to black magic is white magic."
"It rather depends," said Father Brown, "what you mean by white magic."
"I mean silver magic," said the other, in a low voice, like one speaking of a secret revelation. Then after a silence he said, "Do you know what I mean by silver magic? Excuse me a moment."
He turned and opened the central door with the red glass and went into a passage beyond it. The house had less depth than Brown had supposed; instead of the door opening into interior rooms, the corridor it revealed ended in another door on the garden. The door of one room was on one side of the passage; doubtless, the priest told himself, the proprietor's bedroom whence he had rushed out in his dressing-gown. There was nothing else on that side but an ordinary hat-stand with the ordinary dingy cluster of old hats and overcoats; but on the other side was something more interesting: a very dark old oak sideboard laid out with some old silver, and overhung by a trophy or ornament of old weapons. It was by that that Arnold Aylmer halted, looking up at a long antiquated pistol with a bell-shaped mouth.
