Molly pressed her binoculars against the chain-link fence, watching the backyard transform into a princess wonderland. "Seventeen kids confirmed," she whispered. "That's at least thirty presents, maybe forty if Grandma showed up feeling generous." Bill crouched beside her, adjusting his fake mustache for the ninth time. "I still think the clown disguise was a mistake. Kids hate clowns." "Kids fear clowns. There's a difference. Fear equals avoidance. Avoidance equals clear access to the gift table." "What about the parents?" "Parents will be too busy preventing little Timmy from drowning in the bouncy castle." Molly pulled out a crumpled diagram. "You enter through the side gate at exactly two-fifteen, during the cake ceremony. Everyone gathers for the singing." Bill squinted at her drawing. "Is that a dragon?" "That's you, Bill. Focus." "Why do I have a tail?" "It's your balloon animal supplies. You're backup entertainment if anyone gets suspicious." She folded the paper sharply. "Grab the presents, stuff them in the catering van, and we're gone before they finish the second verse of Happy Birthday." Bill sighed heavily. "We're really robbing a seven-year-old." "We're redistributing wealth, Bill. Now put on your rainbow wig."
