Molly unfolded the crayon map across the alley dumpster, weighting one corner with a half-eaten cupcake. Bill adjusted his black turtleneck, which squeaked because it was actually a wetsuit. "Security?" Molly whispered. "Three grandmothers, one magician, and a bouncy castle," Bill said. "The castle worries me." "It should. Inflatable fortifications are notoriously unstable." Bill tapped the drawing. "We enter through the petting zoo, disguise ourselves as goats, mingle, then grab the presents." "Goats don't carry sacks." "These goats have ambitious careers." Inside the community hall, children shrieked at musical chairs. Balloons bobbed like tiny informants. Molly peeked through the door and frowned. "New problem," she said. "Every present has a name tag." "So?" "So stealing Connor's spaceship from Connor feels personal." Bill sighed. "Fine. We steal only the untagged ones." "There aren't any." "Then we steal the cake." Molly watched a toddler hug a lumpy package as if it contained the moon. Her shoulders softened. "Bill, we're monsters." "We are professionals." "We're professional monsters." A magician produced a rabbit. The rabbit stared at Bill judgmentally. Bill zipped his sack closed, empty. "Retreat?" "Retreat," Molly said. "But take a balloon. For evidence." They fled, pursued only by music and shame.
