Molly adjusted her floppy clown wig and glared at Bill across the rickety card table. “This is the dumbest idea you’ve ever had, and you once tried to rob a funeral.” Bill grinned, waving a brightly colored blueprint that was actually a children’s party invitation. “Think about it, Mol. Twenty screaming kids, one stressed-out magician, and a mountain of wrapped presents under a bouncy castle. It’s practically begging to be heisted.” “We’re not wearing the matching penguin suits again,” Molly said, folding her arms. “Last time I almost got licked to death by a toddler.” “That was character building,” Bill replied, sliding her a tiny plastic saxophone. “You wear the suit, I work the crowd. I’ll shout ‘Who wants to see a magic trick?’ and while they’re all watching the rabbit explode into glitter, you shove the loot into the fake cake.” Molly pinched the bridge of her nose. “Bill, if we get recognized at a children’s party we’ll be on every ‘Worst People Alive’ list by dinner.” Bill leaned in, eyes sparkling with criminal joy. “Exactly. No one will suspect seasoned thieves would sink this low. It’s genius. We’re stealing joy, Mol. And maybe a couple of those big Lego sets while we’re at it.” She sighed, already reaching for the ridiculous polka-dot bow tie. “Fine. But if I have to sing Happy Birthday, I’m keeping the entire piñata for myself.”
