Molly studied the suburban house through binoculars, where balloons bobbed above the fence like colorful surrender flags. Bill crouched beside her in a tuxedo two sizes too small, his beard disguised beneath a glittering unicorn mask. They had spent three weeks constructing the perfect operation: arrive during musical chairs, bypass the suspicious grandmother, and evacuate the loot in a wagon labeled Free Puppies. “Once the cake falls, we grab everything,” Molly whispered. “Even the enormous box?” Bill asked. “Especially that one,” Molly said. “Or a bicycle,” Bill suggested. “Then pedal faster,” Molly ordered. After cake fell, children stampeded toward piñata. Molly slipped through gate. Bill followed as uncle. Inside, presents towered beneath HAPPY BIRTHDAY, TODD. Molly produced wire cutters, a smoke bomb, and cupcakes. Bill grabbed package but a toddler blocked him with a sword. He surrendered a cupcake; toddler screamed. Aunties turned. DJ started a conga line. Molly seized wagon and sprinted. Bill piled presents into it, leading parents through kitchen. They burst outside, chased by children and a grandmother fast enough to qualify as transportation. In alley, Molly inspected haul. Packages read TO TODD, FROM GRANDMA. The masterpiece contained socks and a sweater large enough to conceal Bill.
