Molly unfolded the crayon-scribbled map across the dashboard of the van. A smear of jam marked the community hall, and Bill, wearing a party hat he claimed was “reconnaissance,” squinted at it like a general before battle. “Right,” Molly said. “We go in during the cake song.” “You mean ‘Happy Birthday’?” “I don’t use brand names on jobs.” “It’s not a brand name, Molly. It’s a song.” “It’s a trap, Bill. Everyone’s distracted, everyone’s emotional, and Aunties are filming vertically. Perfect window.” Bill nodded gravely. “And the presents?” “Stacked by the inflatable unicorn, according to our source.” “Our source is a six-year-old with frosting in his ear.” “Reliable. Greedy, but reliable.” Bill adjusted his party hat. “I still think this is low, even for us.” “Low? Bill, last week you stole a wishing well.” “It was unattended.” “It was bolted to a courtyard.” “It wished to be free.” Molly tapped the map. “Focus. We enter as entertainers.” “What kind of entertainers?” “Magicians.” Bill looked down at his costume: black cape, fake mustache, trainers with squeaky soles. “Can you do magic?” “I can make rent disappear.” “That’s not a trick, that’s bookkeeping.” “You’ll be my assistant.” “I don’t fit in a box.” “You don’t have to fit in a box. You have to look mysterious and say ‘ta-da’ whenever something goes wrong.” “So constantly.” “Exactly.” Through the windscreen, children shrieked inside the hall. A balloon bounced against the window, followed by a small face pressing its nose to the glass. Bill waved. The child waved back, then vanished. Bill swallowed. “They look… cheerful.” “That’s because they haven’t seen the gift table vanish yet.” “Do we have to take all the presents?” “That’s the job.” “Who hired us again?” Molly checked her notebook. “Anonymous client. Paid in advance. Left a note that said, ‘Ruin Tyler’s party.’” Bill frowned. “Molly.” “What?” “Tyler is six.” “Age is no defense against having too many presents.” “What if the anonymous client is another child?” “Then we’re encouraging enterprise.” “What if it’s Tyler’s jealous cousin?” “Then we’re supporting family drama.” “What if it’s Tyler’s mum trying to avoid assembling noisy toys?” Molly paused. “That one I respect.” Bill leaned closer to the window. “There’s a tiny pirate in there sharing crisps with a dinosaur.” “Sentimental observation logged and ignored.” “The dinosaur just gave the pirate the bigger crisp.” “Bill.” “I’m saying perhaps we don’t rob children.” “We’re thieves.” “We could rob adults.” “Adults lock things.” “Children cry, Molly.” Molly looked at the hall. A chorus of small voices began the birthday song, ragged and joyful. Bill whispered, “That’s our window.” Molly didn’t move. “Molly?” “I’m thinking.” “That’s new.” “I’m thinking maybe we go in, do three terrible magic tricks, accidentally spill juice on the anonymous client if we identify them, and leave the presents alone.” Bill brightened. “A moral pivot?” “A temporary reputational experiment.” “And the fee?” “We keep it.” “Is that ethical?” “We’re not saints, Bill.” He grinned and opened the van door. “Ta-da?” Molly grabbed a bouquet of balloon animals from the back seat. One looked like a sausage having a crisis. “Ta-da,” she said. “And if anyone asks, we’re here to steal the show.”
