Molly tapped the blueprint with a pencil. "Okay, Bill. The Henderson birthday party is at seven. Forty kids, one bouncy castle, and roughly three hundred presents stacked by the fireplace." Bill squinted at the paper. "Why is there a bouncy castle on the blueprint?" "Because it's a very important bouncy castle. It's the getaway route." "Molly, we are not escaping a seven-year-old's birthday party by bouncing out a window." "We're escaping the same way everyone escapes a party. Through the kitchen, past the cake, and out the back door with a sack of loot." Bill scratched his chin. "And the security?" "One dad named Gary with a clipboard and a whistle." "A whistle? That's terrifying." "That's why we bring the clown." "We don't have a clown." Molly pulled a rubber nose from her coat pocket and snapped it onto her face. "I have a clown." Bill sighed. "Fine. But I'm not wearing the giant shoes again. Last time I tripped over a toddler and apologized to a goldfish." "You were very convincing. The goldfish forgave you." "Goldfish don't forgive anybody, Molly." "This one did. Now, the presents. Every box is wrapped in shiny paper with a name tag. We swap the labels so the nice gifts go to our van and the socks go back under the tree." "Why would we return socks?" "Because the Henderson kids will open them and be heartbroken, and their parents will feel guilty, and nobody calls the police over a guilty feeling." Bill considered this. "That's the most evil plan you've ever had." "Thank you." "Is there a part where we don't get caught?" "Of course. Step three. We hide in plain sight, dressed as the magician's assistants." "The magician's assistants are real?" "The magician is Gary's brother-in-law. He's been paid in cupcakes." Bill groaned and rubbed his temples. "Molly, this plan has a bouncy castle, a clown, and a cupcake-bribed magician." "And it's flawless." "It's a disaster." "Disasters are just flawless plans with better snacks." She grinned and slid a pair of tiny party hats across the table. "Put this on. Nobody suspects the guests." Bill pulled the hat on, sighed heavily, and adjusted the elastic under his chin. "Fine. But if I get stuck in that castle, you're coming in after me." "Deal," Molly said, already reaching for the gift bags. "Now let's go steal some birthday cheer."
