A party of men loaded with new duck-boards is blocked ahead of you. As
you stand there talking to another wayfarer and waiting for the unknown
obstacle to move, a bullet flicks off the parapet a few feet away. It

yellow flicker and a musical whine: "Whine--bang, whine--bang,
whine--bang, whine--bang," just like that spoken very quickly.
