Molly crouched behind the garden hedge, squinting at the glowing living room window, where forty-two presents sat stacked beside a bouncy castle. Bill crawled up beside her, a sack slung over one shoulder and a grin already spreading across his face. "Right," Molly whispered, tapping a crumpled blueprint. "We slip in through the kitchen, grab every gift with a bow on it, and vanish before the birthday cake comes out." "What about the clown?" Bill asked. "Clowns don't count. Nobody looks twice at a clown." "That one's staring at me." "Ignore him. And Bill, why are you wearing a unicorn onesie?" "Camouflage." "You look like a giant glitter marshmallow." "Nobody suspects a unicorn, Molly. Besides, I'm a professional." Somewhere inside, a balloon popped. Both thieves froze, hearts hammering against their ribs, as a chorus of shrieking children erupted in delight. The clown bellowed a cheerful laugh that made the hedge tremble. "Go, go, go!" Molly hissed, sprinting for the back door. Bill tripped over a garden gnome, bounced off a trampoline, and landed face-first in a pile of pink party favors. "Still think I'm a professional?" he groaned. "Shh," Molly whispered, grinning as she yanked him upright. "Grab the pony piƱata on your way out."
