Molly crouched behind the dumpster, squinting at the clipboard in her lap. "Okay, Bill. The party is in the community hall on Maple Street. Forty-two children, one clown, and approximately nine tons of presents stacked by the piano." Bill adjusted his fake mustache, which kept drooping toward his left ear. "Nine tons? Molly, that's a lot of Lego." "It's a lot of everything. Birthday gifts, a bouncy castle, and I'm pretty sure one pony." "A pony?" Bill's eyes lit up. "We could sell a pony." "We are not stealing a pony, Bill." He sighed and pulled a crumpled blueprint from his jacket. "Fine. So what's the plan? Do we go in through the kitchen?" "The kitchen is guarded by Mrs. Pemberton. She's sixty-eight, carries a whistle, and once arrested a raccoon." "Good grief. Then the skylight?" "Bill, you're six foot four. You got stuck in a mail slot last Tuesday." "That was a misunderstanding about the mail slot." He pointed at the blueprint. "Then the back window. It's tiny, but I've been practicing my slither." Molly stared at him. "Your slither looks like a seal having a seizure." "It's an art form." A distant chorus of children erupted inside the hall, followed by the unmistakable wail of a bagpipe. "Who brought bagpipes to a seventh birthday?" Bill whispered. "Apparently the birthday boy's grandfather. Look, we'll go in during the cake cutting. Everyone will be staring at the frosting, not the presents." "Brilliant. Like a magic trick." "Exactly like a magic trick. You're the distraction. You'll be the clown." Bill froze. "I am not going in as the clown." "You already bought the costume." "I bought it for Halloween, Molly. It's a sad, tiny costume. It barely covers my knees." "Then you'll be a very memorable clown." He groaned and reluctantly pulled a red nose from his pocket. "If I get arrested, I'm telling everyone you planned this." "Fine. And if we get away clean, we split the Lego." "Deal." He snapped the nose onto his face. "Honk." Molly rolled her eyes and tucked the clipboard under her arm. "Let's go steal some presents from children, Bill." "Stealing from children is a crime." "It's a crime against the Lego." "Fair enough," Bill said, and they slipped toward the back window, one very tall, very wobbly clown and one determined thief.
