The van smelled of stale cheese puffs, which Bill insisted was reconnaissance and not lunch. "Right," Molly said, unrolling a napkin across the dashboard. "This is the Hendersons' back garden. This blob is the bouncy castle. This smaller blob is where I spilled coffee, so we'll pretend it's a pond." "They don't have a pond." "Then it's a hazard of unknown origin. Stay out of it." Bill squinted at the napkin. "Why is the bouncy castle so central to the plan?" "Because it's central to the party. Twenty-two children, all of them airborne, none of them watching the gift table." Molly tapped the napkin. "The gift table is here, under the gazebo. Nine o'clock, the cake comes out. The candles go on. The lights go down. And for approximately forty seconds, every adult in that garden will be filming a four-year-old inhale a fire hazard." "Forty seconds isn't long." "Forty seconds is an eternity, Bill. Empires have fallen in forty seconds." "Empires have not fallen in forty seconds." "The point," Molly said, "is that we're in, we're loaded, we're gone before anyone's finished singing." Bill chewed his lip. "And the dog?" "What dog?" "There's a dog. Large. Beige. Emotionally unpredictable." He held up his phone, showing a photograph of an enormous animal wearing a party hat with visible resentment. "That's Muffin." "Muffin is not a threat." "Muffin is eleven stone." "Muffin," said Molly, producing a vacuum-sealed packet from her coat, "is a business partner who hasn't been briefed yet. Premium smoked brisket. Muffin will love us. Muffin will write us into her will." Bill looked mildly reassured, then immediately less so. "And the costumes?" Molly reached into the back and dragged forward a bin bag. She pulled out a lurid tangle of purple fur, two enormous felt feet, and a head with a permanent, unsettling grin. "Absolutely not," Bill said. "Nobody questions an entertainer. Nobody asks the dinosaur for identification." "That is not a dinosaur. That is a bear with structural problems." "That is Bingo the Party Pal, and you are Bingo the Party Pal, and Bingo the Party Pal carries a large sack of balloons that will, at approximately nine oh one, contain forty-two wrapped presents and a Nintendo." "Why do I get the suit?" "Because I'm the one who talks, and you're the one who sweats." Bill held the head up and stared into its dead plastic eyes. "What if a child hugs me?" "Then you hug them back, briefly, with dignity, and you continue toward the gazebo." "What if it's the birthday boy?" Molly paused. "Then you wish him many happy returns. We're thieves, not monsters." Bill sighed and pulled the head over his own. His voice came out muffled and tragic. "This smells like a wet armchair." "You look wonderful." "I can't see anything below my chin." "Then follow the sound of my voice and the smell of brisket." Molly checked her watch, folded the napkin, and slid it into her pocket like a treasured map. "Eight fifty-two. Let's go earn Christmas." She opened the door. Somewhere over the fence, twenty-two children shrieked in unison, and Bingo the Party Pal walked bravely toward them, feet first.
