The van smelled of stale pretzels and ambition. Molly had parked three houses down from the Henderson backyard, where a crowd of sugar-crazed seven-year-olds was screaming inside a giant inflatable castle. Bill sat in the passenger seat, clutching a clipboard labeled OPERATION SPARKLE in marker. "Okay," Molly whispered, tapping the blueprint taped to the dashboard. "The bouncy castle is our perimeter. Nobody gets past the bouncy castle." "Why is the bouncy castle our perimeter?" "Because it's a bouncy castle, Bill. It's the most secure structure in the county." Bill squinted at the crayon-drawn map, which showed a house, a sun, possibly a dog, and a large red X labeled PRESENTS. "And where's the gift table?" "Under the gazebo, right beside the cake. We go in dressed as clowns." "We're not dressed as clowns." Molly reached behind her seat and tossed him a rainbow wig. It landed squarely on his face. He peeled it off slowly, the way a man removes a wet sock. "I'm not wearing the wig." "You're wearing the wig. Nobody suspects a clown. Adults don't even see clowns. It's like being invisible with a squeaky shoe." "I don't have a squeaky shoe." "You do now. I bought them for you." She produced a pair of enormous yellow shoes, and Bill sighed like a man signing his own confession. Ten minutes later, they crept across the lawn. Molly had a rubber nose strapped on, and Bill's oversized shoes slapped the grass with every step. A golden retriever trotted over, sniffed the wig, and sneezed directly into his ear. "Shh," Molly hissed. "We're professionals." "Professionals don't get sneezed on by dogs." "Professionals roll with it." They reached the gazebo, where a mountain of glittering boxes sat beneath paper streamers. Bill's eyes widened. He began stuffing a sack with the biggest packages he could carry, one of which was shaped suspiciously like a bicycle. "Are you the entertainment?" Molly froze. A small boy in a cowboy hat stood beside them, holding a juice box. "Yes," Molly said. "We are the entertainment." "Can you do a trick?" Bill, panicking, pulled a sock puppet from his pocket and made it bow. The boy shrieked with joy and sprinted off to get his friends. Within seconds, six children surrounded them, chanting for more. "Molly," Bill whispered through the wig. "I think we've been booked." "Then we perform," she said, snatching a balloon from the table. "Nobody leaves until those presents are in the van." Twenty minutes later, the party was a triumph. Bill had juggled three oranges, Molly had folded a balloon into a surprisingly accurate giraffe, and the sack was nearly full. Then a unicycle rolled up the driveway, and a tall man in full clown makeup climbed down, glaring at them with burning fury. "Those," he said, pointing at the yellow shoes, "are my shoes."
