Molly spread the blueprint across the hood of the van. It was, technically, a placemat from Chuck E. Cheese. "Ball pit's here," she said, tapping it. "Presents stack against the west wall. We go in at cake, out by candles." Bill frowned. "Why cake?" "Because during cake, thirty children are screaming at a woman in a mouse costume. Nobody's watching the loot table." "I don't like it. There's a clown." "There's always a clown, Bill." "This one does balloon animals. Fast." He held up his hands, which shook slightly. "I saw him make a giraffe in four seconds. That's not a hobby, Molly, that's a warning." She sighed and rolled up the placemat. "You robbed an armored car in Toledo." "Armored cars don't have juice boxes and a bouncy castle." He tugged his rented Elmo head over his ears, muffling him. "And this costume smells like regret." "You look adorable. Menacing, but adorable." Molly checked her watch. "Ninety seconds. Remember, if anyone under four feet tall speaks to you—" "I say I'm Elmo's cousin, Todd." "Perfect." They crossed the parking lot in perfect silence, two professionals, one of them waving cheerfully at a toddler who screamed and screamed until his mother apologized.
