Molly had drawn the floor plan on a napkin stolen from a funeral buffet, because she believed in recycling and poor omens. Bill leaned over it, dripping doughnut glaze onto the labelled square marked CAKE, which, in his defense, looked delicious even in biro. Across the street, the community hall throbbed with shrieks, whistles, and the tinny menace of a magician failing to control seven-year-olds. Presents glittered beneath a banner reading HAPPY BIRTHDAY, OSCAR!, a mountain of rockets, robots, and suspiciously book-shaped disappointments. “Molly, clowns distract; we enter by bouncy castle during lunch,” Bill whispered. “Fine, but no balloon animals in getaway van, ever again,” Molly said. Their equipment lay in a gym bag: lock picks, party hats, two fake invitations, and a piñata costume with eyeholes cut at criminally uneven heights. The plan required dignity, silence, and someone small enough to crawl beneath the gift table, so naturally Bill had nominated Molly and eaten her emergency biscuit. She adjusted her sequined mask, checked the wind, and watched a toddler weaponize jelly. Bill saluted with a sausage roll. The heist, she feared, was already sticky. Behind them, a banner sagged ominously, as if even crepe paper recognized bad life choices.
