Molly spread the blueprints across the kitchen table. They were drawn in purple crayon. "Where did you get these?" Bill asked. "The birthday invitation. There's a map on the back so parents can find the bouncy castle." Bill squinted hard. "Is that a dragon?" "That's the garage." He nodded slowly, as if this made perfect sense, and adjusted his balaclava, which he had knitted himself and which was slightly too small. His ears poked out like pink handles. "So what's the plan?" "We go in disguised as clowns," Molly said. "Nobody questions a clown. Nobody even looks at a clown directly." "I don't know any tricks." "Fall over a lot. Children love that." Bill considered this. He fell over a lot anyway, mostly off fences, so it seemed within his skill set. "And the presents?" "Stacked by the cake table. Thirty minimum. We wait for the piƱata, then grab everything while they're distracted by sugar." "What if the kid sees us?" Molly lowered her voice dramatically. "Timmy is seven. He has a lisp and a whistle. We can take him." Outside, a small boy in a superhero cape pressed his face against the window, took careful notes, and blew his whistle.
