Rain drummed on the van roof while Molly unfolded a blueprint across the dashboard. It was printed on the back of a pizza menu and smelled faintly of pepperoni. “Target?” Bill asked. “The Rainbow Kingdom Birthday Extravaganza,” Molly said. “Eight-year-old named Dexter. Forty-two presents. One chocolate fountain. Three exits.” Bill squinted at the drawing. “Why is the cake marked as a security checkpoint?” “Because it has a clown beside it.” “A clown isn’t security.” “This one has a laminated badge.” Through the windshield, the children’s party glowed inside the community hall. Balloons bobbed against the windows. A banner announced HAPPY BIRTHDAY, DEXTER! in letters that appeared to have been cut by someone wearing oven mitts. Molly tapped the blueprint. “We enter through the rear loading door at 1400 hours, disguised as entertainers. I distract the adults. You secure the presents.” “What are we disguised as?” “Magicians.” Bill looked down at his costume: black trousers, a velvet cape, and a top hat with a feather stuck to it. “I thought we were disguised as clowns.” “That was before I saw the clown.” A shriek rose from inside, followed by applause and a loud electronic voice announcing, “Please do not put the hamster in the balloon sculpture.” Bill swallowed. “Maybe we should steal the balloon sculpture.” “Focus. The presents are stacked beneath the mural of a smiling sun. We take the large ones first, then the suspiciously heavy ones.” “How do we know which are suspicious?” “Shake them.” “What if the children are watching?” “Then shake them confidently.” They slipped through the rear door behind a delivery man carrying twelve pizzas. Molly smiled at the nearest adult, who immediately handed her a paper crown. “Happy birthday,” the woman said. “Are you the entertainers?” “Absolutely,” Molly replied. Bill bowed. His hat fell off, revealing a rubber chicken inside. “Magic!” he announced. A cluster of children gathered. Molly produced three scarves from her sleeve, then accidentally pulled out a sock, two receipts, and a small screwdriver. “Observe,” she said, stuffing everything back. “The ancient illusion of financial instability.” The children roared. Bill edged toward the presents. A girl blocked him. “What’s your magic trick?” “I can make this gift disappear.” “Which one?” Bill pointed to a box wrapped in silver paper. “That’s mine,” she said. He froze. “Excellent. Then I can make myself disappear.” “You already look like my uncle.” Molly snatched up a balloon and whispered, “Abort.” “Why?” “The clown is coming.” The clown approached, badge gleaming, carrying a clipboard. “I’m checking party staff.” Bill shoved a present under his cape. “We’re not staff.” The clown leaned closer. “You’re thieves.” Molly’s eyes narrowed. “How did you know?” “You left the van running.” For one tense second, nobody moved. Then the chocolate fountain tipped, cascading across the floor. The children cheered as if witnessing a miracle. Molly grabbed Bill’s sleeve. “Now.” They sprinted through the kitchen, presents bouncing beneath their capes, while the clown slipped on chocolate and the adults applauded, assuming it was part of the entertainment. Outside, Bill opened the stolen box. A dozen pairs of socks stared back. Molly sighed. “We stole laundry.” Bill considered them. “Still warmer than prison.”
