Rain ticked against the van roof while Molly unfolded a crumpled map of the neighborhood. Bill peered over her shoulder, wearing a burglar’s mask that was clearly meant for a raccoon. “Tonight,” Molly whispered, “we infiltrate the birthday party, locate the presents, and leave before anyone notices.” “Excellent,” Bill said. “What’s the disguise?” “Something inconspicuous.” Bill held up a glittery purple cape. “I’m a wizard.” “You’re a delivery driver.” “A wizard delivery driver.” “The party is for six-year-olds, Bill. You’ll blend in.” Molly pointed to the map. The house sat at the end of a cul-de-sac, festooned with balloons and a banner reading HAPPY BIRTHDAY, TREVOR! A plastic dinosaur guarded the walkway, its open jaws full of rainwater. “We enter through the side gate,” Molly said. “The cake table is here. Presents are stacked beside the sofa. We grab the largest boxes first.” “What if there are adults?” “There will be adults.” “Armed?” “With juice boxes and opinions.” Bill nodded gravely. “A dangerous combination.” They crept across the lawn. Bill’s cape snagged on a rosebush, and Molly had to tug him free while he apologized to the plant. From inside came music, shrieks, and the unmistakable roar of someone pretending to be a dinosaur. At the side door, Molly produced a hairpin. “Can you open it?” Bill asked. “It’s already open.” “That’s less impressive.” “It’s also faster.” They slipped inside and found themselves in a hallway crowded with tiny shoes. A toddler in a cardboard crown stared at them. “Are you the magicians?” he asked. “Yes,” Molly said. “No,” Bill said. The toddler frowned. “You’re bad magicians.” “Precisely,” Molly replied. “We specialize in disappointing entrances.” They hurried into the living room. Presents formed a bright, wobbling mountain beneath a banner. Molly reached for a remote-controlled race car. “Take the big boxes,” she whispered. Bill lifted a package wrapped in dinosaurs. “This one feels promising.” “It’s probably socks.” “For a child?” “Children need socks.” A woman carrying a bowl of popcorn approached. Molly shoved the race car behind her back. “Can I help you?” the woman asked. “We’re with the entertainment,” Bill said. Molly smiled tightly. “He’s the entertainment.” Bill flourished his cape and accidentally knocked over a balloon. It burst with a crack like a gunshot. Everyone in the room fell silent. Then the birthday child shouted, “Again!” The children cheered. Bill bowed. “Thank you. I’ll be here until arrested.” Molly grabbed his sleeve. “New plan. We perform, then steal the presents during the applause.” “Do you know any magic?” “I can make a wallet disappear.” “Whose?” “Yours, if you keep asking questions.” They launched into the worst magic act in party history. Bill pulled a rubber chicken from his cape. Molly produced three spoons and no explanation. The children roared. Adults applauded politely, then enthusiastically when Bill sat on a whoopee cushion. During the commotion, Molly and Bill carried two presents toward the door. The birthday child noticed. “Hey! Those are mine!” Molly froze. Bill sighed. “Fine,” he said. “We’ll give them back.” The child considered this. “You can stay for cake.” Molly glanced at the presents, then at the frosting. “Do we get ice cream?” “Two scoops.” Bill removed his mask. “Molly, we’ve been outbid.” She nodded. “Retreat with dignity.” They left twenty minutes later with full stomachs, unpaid balloon-blowing debts, and a party favor bag containing a plastic whistle. Bill examined it in the van. “Our greatest haul,” he said. Molly started the engine. “Don’t blow it.” He blew it. The sound frightened the raccoon mask off his head.
