"Right, so the clown is our biggest problem," Molly said, spreading the crayon-drawn map across the kitchen table. "The clown?" "He sees everything, Bill. Those painted eyes never close." "Molly, those are fake painted eyes. He has real eyes underneath." "We don't know that for certain." Bill rubbed his forehead. "What's our entry point?" "Bouncy castle. We blend in during the chaos, grab the presents, and exit through the garden gate before anyone sings happy birthday." "We're both forty-three years old." "Hence the disguises." "I'm not wearing a dinosaur costume." "It was either that or fairy princess." "Give me the dinosaur costume." "Smart choice. Now the presents are stacked near the kitchen, which means we pass through the jelly and sandwiches zone." "The what?" "High traffic, Bill. Sticky fingers, screaming children, someone always crying. It's essentially a war zone." "Why are we stealing from a seven year old again?" "Her father owes us twelve hundred pounds." "Right." "Besides, she's getting another party on Sunday. Different grandparents." "She's living better than us." "Considerably. Now focus. The magician arrives at three and everything changes." "Why?" "Nobody watches anything during the magician, Bill. That's our window."
