Molly pressed her ear against the door. "How many kids are we talking?" "Twelve. Maybe fifteen." "Armed?" "With cake forks, yeah." "Don't be cute, Bill. What's the security situation?" "Two parents in the kitchen, one dad manning the grill outside, and somebody's gran doing face painting." "Face painting? That's actually perfect cover." "You want me to get my face painted?" "Butterfly. Nobody suspects a butterfly." "I'm not doing a butterfly." "Fine. Tiger." "The presents are in the corner by the bouncy castle. We grab the haul during musical chairs." "Musical chairs is genius. Total chaos." "I've been casing this joint for three weeks, Molly." "Wait. Three weeks? This is a kid's birthday party, not Fort Knox." "The kid's parents are the Hendersons." "The Hendersons? The ones who—" "Exactly. Last year they gave out full-sized iPads in the goodie bags." "What's in the actual presents?" "Rumor is a limited edition Lego set. The Medieval Castle. Unopened." "That's four grand on eBay." "Minimum." "Okay. I'm in. But I'm the butterfly." "Fine." "When do we move?" "Pin the tail on the donkey. Blindfolds everywhere."
