"Right, so the birthday girl turns six at noon," Molly whispered, unrolling a crayon drawing she'd stolen from the fridge of the house next door. "Is that a map?" Bill squinted. "Did you draw this yourself?" "It's what I had available, Bill." "You drew a unicorn in the corner." "That's the getaway car." "It's a unicorn, Molly." "It has wheels. Focus. The presents will be stacked near the bouncy castle, which goes up at eleven." "And we're hiding where exactly?" "Inside the bouncy castle." Bill stared at her. "We're hiding inside the bouncy castle." "Nobody questions what's inside a bouncy castle before they inflate it." "Grown adults, Molly. We are grown adults." "Grown adults who need money." "Fair point. What about the clown?" "Pedro? He's with us." "You hired a criminal clown?" "I hired Pedro. The criminal part is a bonus." "And the children?" "They'll be distracted by cake." "You seem very confident about that." "Bill, I have never met a child who chose anything over cake. Not once in my life." Bill rolled up the unicorn map and sighed. "I hate that you're right."
