Molly tapped the blueprint of the Henderson mansion. "The party starts at three. Every kid will be in the backyard by three-fifteen, which means the gift room is ours." Bill adjusted his fake mustache, which kept drooping. "And the clown? Is he still hired?" "Yes, and he's our insider. He'll be juggling in the yard to keep the parents distracted." "Good. I brought the duffel bags." Bill held up three enormous sacks, one of them still wearing a tiny unicorn sticker. Molly groaned. "Bill, those are for the loot, not for the kids." "Relax. If anyone asks, we're the balloon twisters." "We don't know how to twist balloons." "Then we'll say we're learning." He grinned. "Besides, nobody suspects a pair of grown adults in matching rainbow wigs." Molly sighed and pulled on her wig. "Fine. But if you sneeze again, we're abandoning the plan." "No promises," Bill said, sneezing directly into a bouncy castle pump.
