"The bouncy castle is the problem," said Molly, spreading the hand-drawn map across the hood of the van. "Why is the bouncy castle a problem?" "Because I drew it too big and now it's covering the back gate on the map." Bill squinted at the paper. "Is that a clown?" "That's a guard." "It's wearing big shoes." "It IS a clown, Bill. They hired a clown. Every party has a clown." "I hate clowns." "Everyone hates clowns. That's not relevant." Molly tapped the map firmly. "We enter through the side garden at two fifteen, when the singing telegram arrives." "They have a singing telegram too?" "This kid's parents are loaded, Bill. That's why we're here." "How many presents are we talking?" "I counted forty-seven through the binoculars." "You were watching a children's party through binoculars?" "Professionally." "That doesn't make it less weird, Molly." "The point is, forty-seven presents, two of us, one van." She rolled up the map. "We're rich." Bill was quiet for a moment. "What if some of the presents are just socks?" "Then we steal the socks, Bill." "Fair enough."
