Behind a privet hedge, Molly and Bill crouched like a pair of hungry foxes. Across the lawn, eleven sugar-crazed children shrieked around a bouncy castle while a clown twisted balloon animals. Near the patio, a folding table sagged beneath a mountain of presents wrapped in shimmering paper. Bill tugged at his rented dinosaur costume, which squeaked every time he moved. The side gate was unlocked. Molly found this deeply insulting. She unfolded the crumpled napkin holding their entire heist plan, which had three steps, two arrows, and a doodle of a unicorn that Bill had insisted on drawing. Their getaway ice cream van idled three streets away, still playing a tinny Happy Birthday on loop. "All of them, Bill," Molly whispered. "Every box, every bow." Bill frowned. "Even the ones from Grandma Ruth?" "Especially Ruth. Her socks are cashmere." Bill nodded solemnly, then bumped the hedge with his tail. Squeak! Every child on the lawn turned. A small boy in a pirate hat pointed his plastic sword at them and declared the dinosaur a thief. Molly sighed and pulled a paper party hat over her ears. Step four, written in tiny letters at the bottom of the napkin, said RUN.
