Molly crouched beside Bill in the hedge, eyeing the glowing bouncy castle where a dozen children shrieked like car alarms. Bill clutched a sack and adjusted his rubber clown nose, which squeaked every time he breathed. "Right. Plan's simple. We break in dressed as entertainers and walk out with every present." "We're not entertainers. I can't juggle." "Nobody checks a clown's credentials." Molly nodded toward the conservatory, where a gift table glowed under fairy lights. "Twenty presents wrapped in dinosaur paper." "How do we tell the good ones?" "Biggest bows. Dads always blow the budget on bows." Bill nodded as if he understood. "And the kids?" "Sugar-crazed gremlins. Nobody notices anything but cake." A small pirate with blue face paint popped out from behind the castle, clutching a sticky lollipop like a cutlass. He squinted at them. "You're not clowns." "We're famous clowns," Molly said, not very convincingly. "Mum said robbers would come." He jabbed his lollipop at the sack. "Everything on that table is socks from Auntie Pat. The real presents are in the shed. Fifty-fifty, or I scream." Bill groaned, and his nose squeaked in indignant protest. "Nine years of crime, and I'm being blackmailed by a pirate."
