Molly crouched behind the inflatable castle like a panther in borrowed sequins, studying the suburban battlefield. Beyond the hedge, balloons bobbed above a lawn swarming with sugar-drunk children, distracted parents, and one clown who looked morally flexible. Bill, wedged beside her in a van labeled TINY PONY PETTING ZOO, unfolded the party map with the solemnity of a general and the sneeze of a man allergic to ambition. The presents sat under a gazebo, stacked in bright paper towers, each one practically winking at crime. "Smile and wave," Molly whispered. "You distract the clown. I grab presents. No heroics, Bill." "I hate heroics," Bill whispered back. "I prefer planning, quietly." A sprinkler clicked on and soaked his shoe. He glared at it as though betrayed by plumbing itself. Molly adjusted her tiara, checked the cake knife in her boot, and timed the chaos: piƱata in seven minutes, candles in twelve, parental attention span already collapsing. Somewhere, a child screamed with the high, pure note of a teakettle discovering betrayal. Molly grinned. Every great robbery needed cover. Nothing on earth provided better cover than a birthday party. Bill straightened his fake pony tail and prayed the universe respected audacity disguised as entertainment on a Tuesday afternoon.
