There was a live oak a few feet ahead of us. Thick and gnarled and ancient-looking. That was not new. The playground on our right. Not new, either. But now, a guy wearing a gray suit, slumped against the trunk of the oak tree. Not moving. This was new. He was encircled by blood; a half-dried fountain of it poured out of his mouth. The mouth open in a way that mouths generally shouldn't be. Flies at rest on his pale forehead. "He's dead," Margo said, as if I couldn't tell.
