Molly crouched behind the hedge, binoculars pressed to her eyes, watching the glowing windows of number fourteen Maple Lane. Bouncy castles sagged in the garden, and a cluster of helium balloons bobbed against the gate like nervous ghosts. Beside her, Bill rustled a sack that clinked suspiciously. "Balloons on the gate, bouncy castle in the yard," she whispered. "Bill, this is a fortress made of sugar." Bill adjusted his fake moustache and checked his pocket watch. "Simple plan. We slip through the cat flap, grab every present from the hall table, and vanish before the magic show ends." "The magician has been staring at us for ten minutes." "He's a magician, Molly. They always stare. It's the job." The sack let out a loud squeak. "Quiet, you." Molly lowered the binoculars and glared at him. "What's in the sack?" "Sausages for the dog. Plus a backup plan." "And the backup plan?" "If anyone wakes up, we declare ourselves the entertainment and start juggling." She stared at him for a long moment. Inside the house, a hundred children shrieked with joy, and sparklers hissed like angry bees. Molly sighed, checked her own watch, and started crawling toward the back door. "Cake's in five minutes," she muttered. "Let's go be the most suspicious guests in history."
