“Bill, confirm the target.” “The Rainbow Room. Children’s birthday party. Presents stacked beneath a balloon arch.” “Security?” “Three parents, one grandparent, and a clown with the cold, dead eyes of a bank manager.” “Excellent. Our kind of professional.” “Molly, these are children’s presents.” “Exactly. Small boxes, low shelves, terrible wrapping. We’ll be out before anyone notices.” “Someone will notice. It’s a birthday party.” “Then we disguise ourselves.” “As what?” “Children.” “I’m six foot two.” “Slouch.” “And you?” “I’ll be the birthday magician.” “You don’t know magic.” “I know misdirection. Watch this.” Molly snapped her fingers and produced a cupcake. “Where did you get that?” “From the party.” “We haven’t entered yet.” “Details.” “Plan?” “We arrive wearing matching dinosaur pajamas, claim to be cousins, and join the conga line.” “There is no conga line.” “There will be after I start one.” “Then we grab the presents?” “Not immediately. First, we win trust by applauding loudly.” “I can applaud.” “Can you look delighted by a seven-year-old’s recorder solo?” “I once listened to a tax auditor explain depreciation.” “Perfect.” “And the getaway?” “Balloon-powered laundry cart.” “That is not a vehicle.” “Neither is a clown, yet here we are.” “Fine. But we split everything fifty-fifty.” “Agreed.” “Even the bicycle?” “Especially the bicycle.” “What if the birthday child catches us?” “Then we give the presents back.” “That’s your plan?” “No. That’s our alibi.”
