Molly pressed her binoculars against the chain-link fence, watching a clown twist balloon animals in the backyard. "Twenty-three presents on the table. Maybe twenty-four," she whispered. Bill crouched beside her, adjusting his fake mustache. "That's a lot of Legos, Mol. A lot of Legos." "Focus. We go in through the bounce house. Nobody suspects the bounce house." "I don't know about this one. These are kids, Molly. Little kids with sticky fingers and no concept of personal space." She lowered the binoculars and fixed him with a stare. "Last month you cried when we stole from that retirement home." "Those seniors had stories to tell! Wisdom to share!" "Gerald bit you." "Gerald was confused!" Molly sighed and pulled out a crumpled diagram. "Look, we wait for the piƱata. Every child swarms the candy. We grab the presents. We disappear." "What if someone recognizes us?" "We're dressed as entertainment. You're a magician. I'm a princess. Act natural." Bill smoothed his sequined vest nervously. "The magician costume was your worst idea." "Your card tricks are excellent." "I only know one trick, Molly. One." She patted his shoulder. "Then you better make it unforgettable."
