Molly spread the blueprint across the kitchen table. “Tonight, we infiltrate the birthday party.” Bill squinted at the drawings. “A fortress?” “A suburban living room.” “Any guard dogs?” “Only a grandmother with excellent hearing.” Bill nodded solemnly. “Dangerous. What’s our exit strategy?” “We leave through the back door, carrying the presents.” “All of them?” “That is generally how ‘all’ works.” Bill examined the guest list. “I see a problem. The invitation says costumes required.” “Perfect. We’ll disguise ourselves as pirates.” “Children’s pirates?” “Obviously. Adult pirates attract suspicion.” At eight o’clock, they crouched behind the hedge, dressed as Captain Molly and First Mate Bill. Inside, children shrieked around a cake shaped like a dinosaur. Bill whispered, “The target is twelve brightly wrapped packages.” “Correction,” Molly whispered. “Fourteen. I counted two under the table.” “Your professionalism is inspiring.” They slipped through the open patio door and joined a conga line. A boy pointed. “You’re not from the party!” Molly smiled. “We’re entertainment.” Bill began juggling three balloons. “Very expensive entertainment.” The grandmother approached. “And who invited you?” Molly froze. Bill thrust a present toward her. “We’re from the Department of Birthday Security.” The grandmother narrowed her eyes. “Why are you stealing gifts?” Bill glanced at Molly. “Technically, we’re preventing unauthorized wrapping.” “Put them back,” Molly said. The children cheered as the thieves returned every present, then demanded payment in cake.
