Molly crouched behind the hedge, peering at the glowing windows of number twelve. Balloons bobbed against the glass. Somewhere inside, a clown was losing an argument with a bouncy castle. "Right," whispered Bill, adjusting his ski mask over his bald head. "Plan's simple. We slip in during cake, grab the presents, and vanish." "Simple," Molly said flatly. "You said that about the bank." "The bank was a learning experience." "The bank had a security dog, Bill. Dressed as a bee." "Bees are scary." He pulled a sack from his coat, stitched with the words *Lucky Bag*. "I brought extra room for the bigger boxes." "Those boxes are for a seven-year-old's birthday." "Exactly. Think of the loot. Trains. Walkie-talkies. One of those chocolate fountains." "Bill, that's a child's whole afternoon you're talking about." "And he'll get over it by Tuesday. Trust me." Molly sighed and tugged her gloves tighter. "Fine. But if a single child asks who we are, you do the talking." "Deal," Bill said, then tripped over a garden gnome, which let out a loud, cheerful laugh.
