"Right," Molly said, unrolling a crayon-drawn blueprint across the kitchen table. "The party starts at two. We go in at two-fifteen." "Why two-fifteen?" Bill asked, squinting at the smudged diagram. "Because that's when the clown arrives. Every kid in that backyard will be hypnotized by balloon animals. Nobody watches the present table during balloon animals, Bill. Nobody." "And the parents?" "Wine. By two-fifteen, Karen's already opened the rosé. Trust me on this." "How do we get past the fence?" "We don't go past the fence. We go through the bounce house." "Through it?" "There's a seam on the left side. I tested it Tuesday when I pretended to be a party inspector." "A party inspector isn't a real thing, Molly." "Karen didn't know that. Now focus. You crawl through the bounce house, grab the presents, pass them to me over the fence." "All of them?" "All of them. Even the gift bags." "The gift bags feel excessive." "The gift bags have candy, Bill. Premium candy. Full-size bars." "Full-size?" "These people are rich." Bill leaned back and cracked his knuckles. "I'm in." "You were already in. Put on your disguise." "This is a Spider-Man costume." "Exactly. You'll blend right in."
