Molly tapped the blueprint with a chewed pencil. "The party's in the Hendersons' backyard. Forty kids, one bouncy castle, and a piñata shaped like a unicorn. The presents are stacked on the patio table behind the lemonade stand." Bill squinted at the paper, then at the cardboard box he was holding. "Why is there a unicorn piñata on the blueprint?" "Because it's a security measure, Bill. Nobody robs a house with a unicorn guarding it." "The unicorn isn't guarding anything. It's just hanging there." "Exactly. That's the genius of it. Nobody suspects a unicorn." Molly flipped the page. "Now, the plan. You go in through the side gate, wearing the clown costume." Bill looked down at the enormous polka-dotted outfit folded across his arm. "The clown costume is itchy." "Clowns are supposed to be itchy. It's the whole point. Kids are scared of clowns, so the parents will stay inside, and the kids will run the other way." "That's not how it works. Last time I wore this, a four-year-old bit my shoe." "Then wear better shoes." Molly sighed and pointed at a sketch of the patio. "Once you've distracted the kids with balloon animals, I'll sneak under the table and grab the presents. Every gift with a bow. Every box with glitter on it." "Why glitter?" "Glitter means expensive. Trust me, the rich ones always wrap in glitter." Bill frowned. "Molly, these are seven-year-old birthday presents. The good stuff is probably just a pack of gum and a plastic whistle." "Some of those whistles are collectibles." "Nobody collects whistles." "A lot of people collect whistles, Bill. Don't judge the whistle community." He sighed and tucked the box under his arm. "Fine. What's the escape plan?" Molly grinned. "We load everything into the bouncy castle and roll it out the back gate." "The bouncy castle is still inflated?" "It's a party, Bill. It's always inflated." "And the unicorn?" "The unicorn comes with us. He's our lookout." Bill stared at the box, then at her. "We are two grown adults planning to steal birthday gifts from children." "Yes," Molly said cheerfully. "And we are going to be legends."
