Molly spread the crayon-drawn map across the bonnet of their van, which was disguised, unconvincingly, as a mobile library. The target sat across the street: a garden full of balloons, bunting, sugared children, and a mountain of presents stacked beside a bouncy castle shaped like a dragon with indigestion. Bill adjusted his fake clown nose and squinted through binoculars. “We nab gifts, not cake, understood?” Molly tapped the map with a liquorice stick. “Focus. Enter as entertainers.” Behind them, the van coughed out a puff of glitter from the exhaust. Neither mentioned it. Last week’s robbery of the craft shop still clung to everything. The birthday boy’s father emerged carrying juice boxes like a nervous waiter in a tiny war. Bill frowned. “What if they ask us juggling?” “Then juggle,” Molly said. “With what?” Molly opened a sack. Inside were rubber chickens, three plungers, and a framed photo of Bill’s mother. Bill sighed. Their plan was simple: perform terrible magic, herd the children toward the bouncy castle, wheel the presents into the van, and vanish before anyone noticed the library had no books. Across the street, a child pointed. “Clowns!” Molly grinned. The dragon deflated loudly, like fate changing its mind.
