For a dozen paces he moved rapidly and unevenly, then the natural result occurred. He collided with a man coming in the opposite direction.

The shock was abrupt. Both men swore simultaneously, then both laughed. The whole thing was casual, but Chilcote was in that state of mind when even the commonplace becomes abnormal.
