"Right, so the birthday girl turns six at two o'clock," Molly whispered, unrolling a crayon-drawn map across the kitchen table. "Why do you have a map drawn in crayon?" Bill asked. "I drew it on site. I had to blend in." "You're forty-three." "Children trust me." "Children fear you, Molly." "Same thing. Now focus. The presents are stacked near the bouncy castle." "There's a bouncy castle?" "Don't get excited." "I'm not excited." "You're doing your excited face." "I don't have an excited face." "Bill, we're stealing from children. Compose yourself." "Right, yes. Sorry. How do we get past the clown?" "There's a clown?" "Big one. Suspicious eyes." "All clown eyes are suspicious." "These are particularly suspicious. He looked at me like he knew things." "He's a clown at a birthday party, Bill, he doesn't know things." "Famous last words." "We go in at cake time. Everyone looks at the cake." "And if someone spots us?" "We grab a balloon animal and act natural." "Act natural while holding a balloon animal." "Exactly." "This is the worst plan you've ever had." "Top five, maybe."
