Molly crouched behind the hedge, binoculars pressed to her eyes. Across the lawn, a bouncy castle shaped like a unicorn wobbled in the breeze. "Forty kids," she whispered. "Twelve parents. One clown." "I hate clowns," Bill said, adjusting his balaclava. It was pink. It had been the only one left at the shop. "Focus. The presents are on the table by the cake. In eleven minutes they sing Happy Birthday, and everyone stares at the candles." "Why are we robbing a six-year-old?" "Because her father owes me money, Bill, and he never pays. Also, she's getting a pony-shaped tablet. I've seen the list." Bill frowned. "How do we get past the clown?" "You distract him." "With what?" "Balloon animals. You're going to challenge him to a balloon-off." "I can't make balloon animals." "Then make him feel inadequate. Improvise." Bill sighed, cracked his knuckles, and eyed the unicorn castle. "What if the kids see me?" "You're wearing pink and standing next to a unicorn. They'll think you're part of the show." A tiny voice piped up behind them. "Are you the entertainment?" They turned. A girl in a tiara held out a juice box. "Yes," Molly said smoothly. "This is Balloon Bill." Bill groaned and accepted the juice box.
