Molly adjusted her binoculars and peered through the hedge at the birthday party across the street. A bouncy castle wobbled beside a mountain of gift-wrapped boxes. "Forty-seven presents," she whispered. "Seven-year-old named Trevor. Clown arrives at two." "A clown?" Bill's face went pale beneath his balaclava. "Nobody said anything about a clown." "It's a children's party, Bill. Clowns are standard." "They're standard nightmares. I'll do the vault, the laser grid, the guard dogs. But not clowns." Molly lowered the binoculars. "You once wrestled a crocodile for a diamond." "The crocodile was honest about what it was." She sighed and pulled out a crumpled map drawn in crayon. "Here's the plan. I'll distract the parents by pretending to be the pony handler. You sneak in through the bouncy castle and load the sack." "Why am I in the bouncy castle?" "Because it's the only entrance without a mother guarding it." Bill studied the map. "Why is there a unicorn drawn on the garage?" "That's the garage. I got the map from Trevor's party invitation." "And the sack?" Molly held up a pillowcase printed with cartoon dinosaurs. "Camouflage." Bill sighed, cracked his knuckles, and whispered, "If I see red shoes, I'm out."
