Molly slid the blueprint across the table, a crayon drawing of a birthday cake with "TIMMY IS 6" scrawled in glitter glue. "This is our target," she said. "Timmy's seventh—sorry, sixth—birthday party." Bill squinted. "That's not a blueprint, Molly. That's a kid's homework." "It's reconnaissance. His mom posted it online. Look, there's a bounce house marked here, and the present table is right by the—" "Molly, we're stealing birthday presents from a six-year-old." "We're stealing birthday presents from forty six-year-olds. It's a group party. Rich neighborhood. Do you know how many Nintendo Switches that is?" Bill rubbed his temples. "We used to rob banks." "Banks have security guards. This place has a clown named Bobo and one distracted babysitter." Molly tapped the drawing. "In and out in ten minutes. I dress as a party clown, you handle the loot bags." "I am not wearing a rainbow wig." "You're wearing the rainbow wig, Bill." "I hate you." "You'll hate me less when we're selling forty unopened LEGO sets by midnight." Bill sighed, grabbing the wig off the table. "If Bobo shows up, I'm blaming you." "Deal," Molly said, already lacing her clown shoes.
