The boys ran in formation, one in front, two behind, like a flock of geese flying south. The leader, a beady-eyed boy, was so focused he didn’t notice the cards splayed on the ground. His shoe landed squarely on a picture of a man hanging upside down. He slid. He lurched forward and fell, bouncing several times on his stomach before stopping with a groan. He moved to get up when another of the boys tripped over him, sprawling to the ground in a tangle of arms and legs.

The last boy hurdled over both. He sped away without looking back, with one officer in pursuit.
