Molly flattened the zoo-themed invitation against the café table with a teaspoon, as if interrogating a giraffe in party hat. Bill peered over his sunglasses, which still had the price tag dangling from one arm, and studied the map of Sprinkles Play Barn. Around them, lunchtime accountants ate soup, unaware that two masterminds were circling a bouncy castle in red crayon. The target was little Oliver Puddington’s sixth birthday, rumored to include a mountain of wrapped treasure beneath a banner reading HOORAY, probably in glitter. Molly had acquired intelligence from a chatty magician and one morally flexible balloon artist. Bill supplied the van, though it currently smelled of onions and regret. "We enter as clowns," Molly said. "No honking," Bill warned. "Fine. You distract the pony. I bag unicorn paper." "Also, absolutely no juggling, Bill," Molly added. Bill gulped twice, audibly. Bill nodded solemnly, jotting notes on a napkin already stained with mustard. Their plan involved fake mustaches, a cake cart, and escaping through the ball pit, where witnesses would be too sticky to pursue. Molly smiled at the invitation. Bill practiced looking innocent and achieved mild indigestion. Outside, a pigeon landed on their getaway bicycle and judged them harshly.
