Molly adjusted her fake mustache and peered through the hedge at the birthday party across the lawn. Forty-seven children screamed around a bouncy castle shaped like a unicorn. Beyond them, on a folding table draped in glitter tablecloth, sat a mountain of gift-wrapped treasure. Bill crouched beside her, wearing a foam dinosaur costume that was two sizes too small. He had insisted it was tactical. Molly had stopped arguing around the time he'd gotten stuck in the car door. "Clown at three o'clock," she whispered. "He's the only real threat." Bill nodded gravely, and his tail knocked over a garden gnome. They both froze. The clown turned, squinted, then resumed twisting a balloon into something that looked vaguely like a tax audit. Molly slid a laminated map from her jacket. She had drawn it in crayon, because the plan required blending in, and because the pens had been in Bill's dinosaur. Arrows marked the route: hedge, juice table, pinata, presents, escape via the wheelbarrow. "Why the wheelbarrow?" Bill asked. "Because presents are heavy and I'm not a monster." Somewhere, a child suddenly wailed. A perfect distraction. Molly grinned, cracked her knuckles, and crept forward, dinosaur trailing behind like an apology.
