Molly crouched behind the hedge, peering through the gap at the glowing bounce house. "Bill, how many kids are in there?" "Thirty-two, according to the invitation," Bill whispered, clutching a clipboard. "And a clown named Sprinkles." "Why would anyone hire a clown named Sprinkles?" "Because he's cheap and he owes the birthday girl's uncle money. Focus. The presents are stacked on the patio table. Forty-one boxes, all wrapped in glittery paper." Molly squinted. "Are any of them labeled 'Do Not Touch'?" "Only the one from Grandma. It's a sweater shaped like a llama." "A llama sweater is worth nothing. Skip it." She tugged a black ski mask over her curls. "What's our entry plan?" Bill tapped the clipboard. "Phase one: we slip through the side gate. Phase two: we distract the guests with the piñata. Phase three: we load the presents into the minivan we borrowed from my cousin." "Your cousin doesn't know he lent us a minivan, does he?" "He's in Ohio. He'll find out in a week." Bill winced. "Probably." A scream of laughter erupted from the backyard. Molly flinched. "Bill, the kids are going to notice. They're not stupid. They're children. Children are merciless." "That's why we bring the piñata." Bill pulled a lumpy cardboard donkey from his backpack. It wobbled dangerously. "Watch. I hang it from the oak tree, the kids swarm it, and while they're screaming, we grab the loot." "That donkey looks like it's been through a war." "It's been through three birthday parties this month. Very reliable." Molly sighed and climbed over the fence. Her sneaker landed in a puddle of something sticky. "Oh, that's disgusting. Is that frosting?" "Shh! Sprinkles is coming." A tall figure in a polka-dot suit lumbered across the lawn, honking a rubber horn. Molly froze. Bill froze. The clown stopped, sniffed the air, and looked directly at them. "Hi, kids!" the clown boomed. "Are you here for cake?" Bill raised his clipboard. "Yes. We're the cake inspectors." "Oh, wonderful! Follow me!" Molly stared at Bill. "Cake inspectors?" "It was the best I had." They trudged after Sprinkles toward the glowing tent, where forty-one presents waited, completely unguarded, beside a table of frosted cupcakes. "Bill," Molly whispered, "this is the easiest heist of our lives." "Don't say that. Every time someone says that, something explodes."
