Molly spread the blueprint across the kitchen table, pinning its corners with four stolen cupcakes. Bill leaned over it. “Why are there frosting stains on the escape route?” “Those are tactical markers.” “They’re chocolate.” “Exactly. The children won’t suspect a diagram decorated with chocolate.” Bill squinted at the drawing. The mansion’s ballroom occupied the center, surrounded by rooms labeled BOUNCY CASTLE, FACE PAINTING, and DANGER: UNCLE RON’S MAGIC SHOW. A red arrow led from the presents to the pantry, then through a narrow passage and out toward the garden wall. “How many guards?” he asked. “Three adults, two teenagers, and one very alert grandmother.” “Grandmothers are the worst.” “This one carries a handbag like it contains a brick.” “It probably contains a brick.” Molly tapped the blueprint. “Our target is every present at the party. We enter disguised as entertainers, gather the gifts, and leave before anyone notices.” “What kind of entertainers?” “I’ll be a clown.” “You hate clowns.” “I hate other clowns. I’m excellent at being one.” Bill lifted a red wig from the floor. “And me?” “You’re the magician.” “I can’t do magic.” “You can make things disappear.” “Mostly by putting them somewhere and forgetting where.” “Perfect. Children love mystery.” They arrived at dusk in a van marked BILLY’S DELIGHTFUL PARTY SURPRISES. Bill wore a purple cape, a crooked top hat, and an expression of profound regret. Molly had painted her face white and added a blue smile that seemed to be fleeing sideways. At the gate, a woman with a clipboard blocked them. “Name?” she asked. “Professor Wobble and Madame Giggle,” said Molly. Bill bowed. “We bring wonder, joy, and moderately priced balloon animals.” The woman checked her list. “You’re not scheduled.” Molly gasped. “Not scheduled? Bill, the children will be devastated.” Bill clutched his chest. “I may never recover.” A small boy appeared behind the woman. “Are you real clowns?” “Painfully,” said Bill. The boy tugged his mother’s sleeve. “Let them in.” Inside, music blared while children ricocheted between tables. Molly began twisting balloons into dogs, swords, and one surprisingly convincing subpoena. Bill approached the gift table, producing scarves from his sleeves. “Observe,” he announced, “the miraculous vanishing present!” He covered a wrapped box with a purple cloth, snapped his fingers, and slid it behind his cape. A girl frowned. “That’s not magic. You just took it.” “An excellent beginning,” Bill said. Molly wheeled over a laundry cart labeled BALLOON STORAGE. “Load everything quickly.” “Should we leave the biggest boxes?” Bill whispered. “Obviously not. Those contain the good stuff.” They stacked gifts beneath balloons and paper streamers. Then Uncle Ron seized the microphone. “Prepare for the grand finale!” Molly froze. “What’s his finale?” Bill glanced toward the garden. “Hopefully not ours.” Uncle Ron pulled a rabbit from his hat. The rabbit immediately escaped, sprinting beneath the gift cart. Every child shrieked with delight and chased it. Molly shoved the cart toward the exit. “Now!” Bill pushed from behind. “I’m stealing presents with a clown and a rabbit. This is not how I imagined crime.” “It’s how crime improves morale.” They burst through the garden gate, gifts wobbling, balloons bobbing overhead like a festive getaway cloud. Behind them, the children cheered. Bill glanced back. “Do you think they noticed?” Molly grinned. “They think we’re taking the presents to the birthday boy.” “And if they catch us?” “Give them a balloon sword.” Bill nodded solemnly. “The perfect defense.” Then the cart’s wheel snapped, and presents spilled across the lawn. Molly sighed. “Plan B.” “What’s Plan B?” “Run faster.”
