Molly spread the crinkled party invitation across the café table like a treasure map, ignoring the frosting smear shaped suspiciously like Portugal. Bill leaned in, wearing a paper crown he'd "liberated" from the display stand, and tried to look tactical instead of adorable. The target was the Peppercorn twins' seventh birthday, a balloon-choked extravaganza at the church hall, rumored to contain twelve wrapped dinosaurs, three glitter laboratories, and one suspiciously heavy box labeled Educational Socks. Molly tapped the hall's sketch with a teaspoon. "We enter as magicians, grin, and vanish gifts before cake." Bill frowned at a doodled clown. "Fine, but no crawling through anything labeled Fun, ever again." Their plan depended on chaos: sugared children stampeding after a piñata, parents debating allergies, and Uncle Graham performing accordion versions of pop songs until mercy became a public issue. Molly would distract the bouncy-castle attendant with fake coupons; Bill would wheel in a laundry cart marked Lost Mittens. Neither mentioned what they would do if a child cried. That was the flaw in every villainous enterprise: tiny faces, enormous eyes, and moral collapse. Still, Molly packed confetti smoke pellets anyway. Bill added sandwiches, because heists required snacks and plausible crumbs afterward.
