“Bill, remember: we’re party entertainers, not burglars until after the jelly.” “Molly, I’m wearing a raccoon mask.” “Children love woodland themes.” “It’s a pirate party.” “Then you’re a sea raccoon. Now, objective: presents.” “All of them?” “Every glittery, ribboned, suspiciously rectangular one.” “What if one is socks?” “Then we donate it to your tragic ankles.” “Molly, these are children.” “Rich children. Last year the birthday boy got a pony with highlights.” “Still, stealing teddy bears feels low.” “We’re not stealing teddy bears; we’re liberating evidence of capitalism.” “Your conscience talks fancy when scared.” “My conscience is in the van eating crisps. Listen: you distract them with balloon animals.” “I only know worm.” “Make twenty worms and call it a safari.” “And you?” “I mingle near the gift mountain, laugh like an aunt, and identify the premium parcels.” “Then what?” “We leave with the magician’s trunk.” “There’s a magician?” “There will be when I put you in a cape.” “I hate capes. They make my neck look dramatic.” “That’s the point.” A squeal rose from the garden. “They’re singing.” “Good. Nobody suspects criminals during ‘Happy Birthday.’” “Except everyone staring at the sea raccoon.” “Smile, Bill.” “Raccoons don’t smile.” “Tonight, they improvise.”
