# The Birthday Job Molly adjusted her fake mustache as she spread the blueprints across the table. "The Henderson residence, Saturday at two o'clock. Thirty kids, zero security." Bill whistled. "What's the take?" "At least forty gift bags. Some kid's bringing a gaming console." "A gaming console?" Bill leaned forward. "Why would anyone bring that to a children's party?" "Rich people," Molly shrugged. "Their logic is broken." "So we go in as clowns?" Bill asked hopefully. "Absolutely not. Last time you were a clown, you got stuck in the ball pit for three hours." "That was one time!" "Bill, the fire department had to extract you." He ignored her. "What if we dress as party entertainers? Balloon animals, face painting, the whole deal." Molly considered it. "That could work. You handle the kids, I'll secure the gifts." "And if Mrs. Henderson shows up?" "We improvise." Molly grinned wickedly. "We're professionals." Bill wasn't convinced. "We're stealing from toddlers, Molly." "Exactly. The perfect crime. Nobody suspects toddler theft." They shook hands as sirens wailed outside.
