Molly spread the blueprint across the diner table, pinning its corners with four stolen sugar packets. “According to this, the birthday party has a clown, a magician, and twelve highly suspicious cupcakes.” Bill squinted at the map. “The cupcakes are suspicious?” “They’re arranged in a circle.” “That’s how cupcakes work.” “Not in a circle around the presents.” Bill leaned closer. The blueprint, drawn on the back of a pizza menu, showed the community hall, the kitchen, the inflatable castle, and a large red X beside a table labeled BIRTHDAY TREASURES. “So we enter through the kitchen, distract the adults, and grab the loot.” “Correct.” “How do we distract the adults?” Molly tapped the magician’s name. “We exploit his professional rivalry with the clown.” Bill nodded solemnly. “Everyone knows clowns hate magicians.” “Actually, magicians hate clowns.” “Everyone knows something.” Across the street, the hall glittered with paper stars. Children shrieked inside while a parent wrestled a balloon animal into submission. Molly checked her watch. “The presents are being opened in twenty minutes.” “Then we have plenty of time.” “We have eight minutes.” “Plenty of time for criminals with discipline.” “You wore two different shoes.” Bill glanced down. “That’s camouflage.” “It’s a left sneaker and a right boot.” “Exactly. Nobody expects a coordinated thief.” They slipped around the side of the building and entered through an unlocked service door. The kitchen smelled of frosting and panic. Bill immediately stepped into a bucket. “Quiet,” Molly whispered. “I’m being extremely quiet.” “You’re standing in a bucket.” “It’s a silent bucket.” “It has a mop in it.” “The mop is silent too.” Molly pulled him free, and they crept toward the main room. Through the doorway, a magician in a purple cape was arguing with a clown beside the gift table. “I’m telling you,” said the magician, “my rabbit did not eat the balloon.” The clown pointed angrily. “Then why is it wearing the balloon as pants?” Molly grinned. “Phase one.” She grabbed a microphone from the snack table. “Attention, everyone! The clown has challenged the magician to a duel of entertainment!” The children cheered. The adults gathered around. The magician produced three flaming cards, while the clown began juggling rubber chickens. Bill sprinted to the presents. Molly followed, carrying two empty laundry bags. “Why are there so many dolls?” Bill whispered. “Because children enjoy dolls.” “Why does this one have a terrifying smile?” “It’s a collector’s item.” A little girl appeared beside them. “What are you doing?” Bill froze. “We’re the present inspectors.” Molly nodded. “Highly trained.” “Can you inspect mine?” “Certainly,” Bill said. He lifted a box and shook it. Something inside rattled ominously. The girl gasped. “That’s my hamster!” Bill carefully set it down. “Passed inspection.” The magician’s rabbit suddenly bounded into the gift pile, wearing a balloon crown. The clown applauded. The children surged forward, surrounding Molly and Bill. “Abort,” Molly said. “Which direction?” “Anywhere!” They fled through the inflatable castle, bounced over the fence, and landed in the alley with one laundry bag between them. Bill opened it. Inside lay a single present and six cupcakes. Molly sighed. “We robbed a birthday party for dessert.” Bill examined the smallest cupcake. “At least the evidence is delicious.” From inside the hall, the little girl shouted, “Come back, present inspectors!” Bill smiled. “I think we’ve been promoted.”
