Molly spread the blueprints across the table, smoothing out the crayon drawings with a frown. "This is the layout?" Bill asked, leaning in. "Why does the living room have a unicorn in it?" "That's a structural pillar. Tommy drew it for us." "Tommy? Our inside man is seven years old?" "He's our inside man because he's seven," Molly said. "Nobody suspects a kid. He'll unlock the back door during the piƱata." Bill rubbed his temples. "Walk me through it. What are we dealing with?" "Forty children. One bounce house. Approximately sixty wrapped presents." "Sixty?" Bill whistled. "What kind of kid gets sixty presents?" "A spoiled one named Madison whose father owns a car dealership," Molly said. "We hit the pile during cake time. Everyone's distracted by the candles." "And security?" "One clown. Goes by Mr. Wiggles." Bill paused. "Mr. Wiggles is the only thing standing between us and sixty presents?" "Don't underestimate him. He does balloon animals and karate. I've seen the flyer." "A karate clown." Bill sat back. "This is the worst job we've ever planned." "It's foolproof," Molly insisted. "We go in dressed as parents. Nobody questions a parent. We mingle, we wait, we strike." "I don't have kids. I don't know how to be a parent." "Just complain about the school district and look exhausted." Bill nodded slowly. "I can do tired. What's the getaway?" "Minivan. I rented one. There's a juice box in the cupholder for authenticity." "You thought of everything." "That's why I'm the brains," Molly said. "Now, the presents go out the back, into the van, and we're gone before they finish singing Happy Birthday." "What if they sing fast?" "Nobody sings Happy Birthday fast, Bill. It's the slowest song in human history. We've got ninety seconds, minimum." Bill scribbled something on a napkin. "And if Mr. Wiggles makes a move?" "Then you handle Mr. Wiggles." "Why me?" "Because you're the muscle, and I'm allergic to clowns." "That's not a real allergy." "It's emotional, and it counts." Molly stabbed a finger at the blueprint. "Tommy says the gift table is here, next to the unicorn pillar. We load fast, no hesitating." "What about the parents?" "They'll be on their phones. Trust me, no adult at a kid's party is paying attention to anything." Bill grinned. "You know, this might actually work." "Of course it'll work. The hard part is the cake." "What about the cake?" "We're stealing that too." Bill blinked. "We're stealing a child's birthday cake?" "It's a four-tier custom cake shaped like a castle. Worth three hundred dollars. We'd be idiots to leave it." "Molly, there's a line, and I think a birthday cake is on the other side of it." "There are no lines in this business, Bill. Only opportunities." She rolled up the blueprints. "Now finish your coffee. We've got a bounce house to infiltrate." Bill stared at his cup. "I never thought my life would come to this." "Nobody does," Molly said. "That's what makes us great."
