Molly pressed her back against the garden fence, clutching a clipboard covered in crayon drawings she'd stolen from a recycling bin as a disguise. "Why do we need a clipboard?" Bill whispered. "It makes us look official." "We're wearing ski masks." "Professional ski masks." Bill peered through a gap in the fence at the bouncy castle, the balloon animals, and a table stacked high with wrapped gifts. A clown was making a poodle out of a long pink balloon. "The clown is going to be a problem," Bill muttered. "Leave the clown to me." "What does that mean?" "I have a plan involving his bicycle horn." "That is not a plan." Molly tapped her clipboard with authority. She had drawn a detailed map of the garden on one of the crayon pages, complete with stick figures labeled ENEMY and PRESENTS and one labeled SUSPICIOUSLY LARGE CAKE. "Why is the cake suspicious?" Bill asked. "Because children jump out of cakes." "That doesn't happen at real parties." "It happened to me once and I've never recovered." Bill looked at her for a long moment. "Let's just go buy our own presents." "Where's the fun in that?"
