Molly pressed her binoculars against the chain-link fence, watching a clown twist balloon animals in the backyard. "This is low, even for us," Bill muttered, adjusting his fake mustache. "Low pays the rent. You see how many kids are in there? That's at least thirty presents. Thirty!" Bill scratched his chin nervously. "What's our entry point?" "The bouncy castle. We go in disguised as party entertainers, wait for cake time when everyone migrates to the dining room, then we hit the present table hard." "And our exit strategy?" Molly grinned, pulling two oversized lollipop costumes from her duffel bag. "Nobody suspects the candy." "You cannot be serious." "Deadly serious. You're the red one." Bill held up the ridiculous costume, its spiral pattern making him slightly nauseous. "I went to Princeton for this." "Princeton taught you to pick locks in under six seconds. Now it teaches you to waddle." A child's shriek of laughter erupted from the party. Bill winced. "Relax," Molly said, patting his shoulder. "We're not monsters. We'll leave the birthday kid's present." "How generous." "I thought so. Now put on your lollipop head. We move in five."
