Molly spread the crayon-drawn map across the getaway van's dashboard while Bill tried to fold himself into a clown costume three sizes too small. The target was not a bank or a museum but seven-year-old Timmy Henderson's birthday party, an event rumored to feature an avalanche of wrapped presents piled dangerously high beside a chocolate fountain. Bill tugged at the squeaky red nose, wincing as elastic snapped against his cheek. Molly tapped the penciled X marking the living room where guardians would be distracted by cake and screaming children. Their plan relied on inflatables, sugar crashes, and Bill's deeply unconvincing balloon animals. Outside the suburban house, minivans lined the curb and a bouncy castle wheezed in the front yard. Molly checked her watch, noting the precise moment parents would sing and close their eyes to make a wish. "Bill, remember the plan? Grab presents, ignore cake." "Molly, I swear these pants will betray us." "Just breathe and smile." Bill attempted a balloon poodle that resembled a deflated sausage, hoping no child would question his credentials. Molly stashed an oversized sack behind the gift table, already imagining the haul of action figures, board games, and glitter-covered unicorns for resale later tonight.
