Molly spread the blueprint across the kitchen table, pinning its corners with four suspiciously expensive cupcakes. Bill leaned over it. “Why is there a drawing of a clown labeled ‘probable security’?” “Because the party is at a clown-themed play center.” “And why is the clown holding a clipboard?” “Because he’s the manager.” Bill studied the map. “This is more complicated than the museum job.” “The museum didn’t have a ball pit.” “The ball pit is our advantage. Nobody suspects adults in a ball pit.” “Everyone suspects adults in a ball pit.” “Not if we wear costumes.” Molly opened a duffel bag. Inside lay two glittering, child-sized superhero capes and a rubber dinosaur head. Bill pointed. “I refuse to wear the dinosaur.” “You refused to wear the ballerina tutu, and we lost the diamond tiara.” “That tutu had a personal grudge.” Molly tapped the blueprint. “We enter during musical chairs, when the children are distracted.” “Children are never distracted. They’re tiny, sugar-powered detectives.” “Then we blend in.” “With whom? The six-year-olds?” “Exactly.” Bill lifted the dinosaur head. “I have a beard.” “Wear the head.” “I also have a mortgage.” “Wear the head more convincingly.” From the hallway came a burst of recorded laughter, followed by a kazoo version of “Happy Birthday.” Bill flinched. “The presents are stacked beside the coat rack,” Molly said. “We grab the bags, cross the snack table, and exit through the emergency door.” “Is it locked?” “No.” “Why not?” “Because it’s an emergency door.” “That feels irresponsible.” “That’s why we’ll succeed.” Bill picked up a cupcake and examined the frosting. “What’s the cover story?” “We’re entertainers.” “What do we entertain?” “Each other.” Molly handed him a cape. It had a yellow lightning bolt and the word “Zoomer” stitched across the back. Bill sighed. “If anyone asks, I’m here for my nephew.” “What’s his name?” “Gary.” “Gary is forty-three.” “Gary is flexible.” Molly checked her watch. “The party begins in ten minutes.” “Do we have a getaway vehicle?” “Of course.” Outside, a battered ice-cream van waited at the curb, its painted cone missing one eye. Bill stared through the window. “This is not a getaway vehicle. This is a confession with wheels.” “It has excellent storage.” “It has a jingle.” Molly turned the key. The van chimed three cheerful notes. Bill looked toward the party center. “I’m beginning to think we should steal something less guarded.” “Like what?” “The cupcakes.” “You already stole four.” Bill smiled. “Then we’re professionals.” Molly opened the door. “Move.” He put on the dinosaur head, which squeaked when he breathed. Together, they marched toward the children’s party, Molly disguised as a superhero and Bill disguised as the least convincing prehistoric creature in organized crime. Behind them, the ice-cream van played its jingle again, loudly announcing their arrival to everyone within three blocks.
