Molly spread the blueprints across the hood of the van. They were, technically, a placemat from Chuck E. Cheese. "Bouncy castle here," she said, tapping it. "Piñata there. Presents stacked on the folding table by the punch bowl." "How many presents?" Bill asked. "Thirty-one. It's a joint birthday. Twins." "Twins." Bill whistled. "That's a lot of Lego." "That's a lot of resale value." "And the guests?" "Nine six-year-olds, four parents, one clown named Bobo who owes me money." Bill lowered his binoculars. "Molly, I want to say something, and I want you to hear it without judgment." "Go on." "These are children." "Rich children," Molly said. "There's a chocolate fountain, Bill. A fountain. Of chocolate. Nobody who owns that is losing sleep over a missing Nintendo." "I had a birthday once," Bill said quietly. "Nobody came. My mother made a cake out of oatmeal." "That's beautiful. Focus." "I'm just saying, maybe there's a bank somewhere—" "Banks have guards. This place has Bobo." Molly handed him a bright red wig. "You're the balloon animals. I'm the face painting. We're inside forty minutes, out with the loot by cake." Bill sighed, examining the wig. "Do I get a nose?" "You get a nose."
