Rain ticked against the van roof while Molly unfolded a crumpled map of the community center. “Tonight,” she whispered, “we enter the children’s party, locate the presents, and leave before anyone notices.” Bill peered at the map upside down. “What if they notice?” “Then we improvise.” “You always say that before something catches fire.” “Only twice.” “Three times.” “The bakery incident was technically steam.” Molly tapped the map. “The party is in the main hall. Presents are stacked beside the cake table. We walk in, act cheerful, collect the gifts, and walk out.” “Collect them for whom?” “For us.” “That sounds less like collecting and more like stealing.” “We are thieves, Bill.” “I know, but usually we steal from people who have insurance and a suspiciously large fountain.” Molly sighed. “These are valuable presents.” “They’re children’s presents.” “Exactly. Small items. Easy to carry. Possibly electronic.” “Possibly socks.” “Then we steal the socks.” Bill looked through the windshield at the community center, where balloons bobbed over the entrance. A paper sign read: HAPPY BIRTHDAY, LUCY! PLEASE NO RUNNING. “Why does the sign say no running?” he asked. “Because children run.” “Then how do we escape?” “Walking briskly.” “Through a room full of children?” “Bill, you’re focusing on obstacles instead of opportunities.” “I’m focusing on the six-foot inflatable dinosaur blocking the door.” “That’s not an obstacle. That’s camouflage.” “You want me to hide inside the dinosaur?” “I want you to wear the dinosaur costume.” Bill stared at her. “There’s a difference?” Molly opened the van’s side door. Inside sat a cardboard box labeled PARTY SUPPLIES, a glittery crown, and a large green dinosaur costume. “Put it on.” “Why do I have to be the dinosaur?” “Because you have the posture.” “What does that mean?” “It means you already lumber.” Bill wrestled into the costume, emerging with tiny felt arms and a head shaped like a smiling cucumber. “How do I see?” “You don’t. That’s part of the charm.” “And you?” “I’ll be the magician.” Molly produced a cape and a top hat. “You don’t know magic.” “I know enough to make presents disappear.” “That’s not magic. That’s theft.” “Stop quibbling over vocabulary.” They crossed the parking lot. Music and shrieks spilled through the walls. At the door, a woman holding a clipboard smiled. “Are you the entertainment?” Molly swept into a bow. “The Amazing Molly and her assistant, Sir Billington.” Bill waved one felt claw. “Rawr,” he said. The woman blinked. “Wonderful. Lucy loves dinosaurs.” “Everyone loves dinosaurs,” Molly said. “Especially near unattended presents.” “What?” “Especially when they’re presented with joy.” Inside, children chased bubbles around a table stacked with brightly wrapped boxes. Bill froze. “There are more children than presents,” he whispered. “Focus.” A boy tugged his tail. “Are you real?” Bill bent down. “Only on weekends.” Molly reached for the nearest gift, but a little girl blocked her path. “That’s mine,” the girl said. Molly’s hand stopped. “Is it?” “It has my name on it.” Bill leaned close. “Molly, I think we’ve made a tactical error.” “Yes,” she murmured. “The presents belong to the children.” “Then what are we stealing?” Molly glanced toward the cake. “The refreshments.” Bill’s dinosaur head tilted. “That is a much better crime.” Minutes later, they fled the party with two cupcakes, a bag of pretzels, and the dignity of people who had been defeated by a seven-year-old with a name tag. At the van, Bill removed the dinosaur head. “Next time,” he said, “we rob a bank.” Molly licked frosting from her glove. “Too risky.” “Fine. A toy store?” “Too tempting.” “What’s left?” Molly considered the empty cupcake wrapper. “A children’s party,” she said, “but we charge admission.”
