Molly spread a crayon map across the van's dashboard, weighting one corner with a stolen cupcake. Bill peered through binoculars at the community hall, where balloons bobbed like suspicious witnesses and a magician unloaded a rabbit cage. "We enter during Happy Birthday, when every adult is filming. You wear the dinosaur suit; I pose as the gift inspector." "Gift inspector? That's not a job." "It is if you carry a clipboard and frown." "Children bite, Molly." Bill adjusted the purple tail folded in his lap. "What about the presents?" "We load them into the laundry cart behind the kitchen. Then we vanish through the bouncy castle tunnel." "That's an inflatable caterpillar." A shriek of laughter burst from inside. Bill swallowed. Molly checked her watch, then handed him a party hat with elastic like a garrote for hamsters. "If a clown challenges us, you improvise." "My improvising got us banned from that aquarium." Bill sighed, fitting the hat over his ears. "After this, we're stealing from adults." "Naturally," Molly said. "Now roar politely." Outside, a paper streamer slapped the windshield while Bill's borrowed tail squeaked against the horn in tiny, tragic honks twice.
