G. K. Chesterton 
The Wisdom of Father Brown 

Two men appeared simultaneously at the two ends of a sort of passage running along the side of the Apollo Theatre in the Adelphi. The evening daylight in the streets was large and luminous, opalescent and empty. The passage was comparatively long and dark, so each man could see the other as a mere black silhouette at the other end. Nevertheless, each man knew the other, even in that inky outline; for they were both men of striking appearance and they hated each other.
