Molly spread the napkin across the diner table and smoothed it flat with the reverence of a general unveiling a battle map. "Behold," she said. "The Kensington residence. Saturday. Fourteen hundred hours." Bill squinted at the drawing. "Why does the house have a face?" "That's not a face, that's the floor plan." "It's got eyes, Molly." "Those are the bay windows." "And a mouth." "That's the porch." She stabbed the napkin with a fork. "Focus. Theme is pirates. Every child arrives with a present. Presents get stacked on a folding table beneath the piƱata. That table, Bill, is our vault. And no vault in history has ever been guarded by twelve six-year-olds and one divorced dad with a Bluetooth headset." Bill sat back and folded his arms. "I've got moral concerns." "You stole a wheelchair." "I *borrowed* a wheelchair, and I gave it back cleaner than I found it. This is different. These are children." "These are the children of hedge fund managers. Do you know what a hedge fund manager buys a six-year-old? Last year a kid in that cul-de-sac got a pony. An actual pony, Bill. Named Sergeant Buttons." "Are we stealing the pony?" "We are not stealing the pony." "Because I'd need a trailer, is all I'm saying. Logistically." Molly closed her eyes and breathed through her nose the way her therapist had shown her. "The plan. You're the entertainment. Captain Bellows, hired pirate. Big hat, big voice, big presence. You keep the kids in the backyard doing the treasure hunt for eleven minutes." "Eleven." "Eleven. Meanwhile I go in through the side door dressed as catering, and the presents go out in a cake box the size of a mini-fridge." Bill picked up his coffee, considered it, and set it down again. "I don't have a pirate voice." "You do impressions constantly. You did the mayor for forty minutes at Christmas." "That was a fluke and a personal low point." He cleared his throat, then rasped, "*Arrr, ye scurvy landlubbers, hand over yer birthday plunder.*" Molly stared at him. "That was frightening." "Was it good frightening?" "It was Australian." "Pirates were basically Australian." "Pirates were *not* basically Australian." She rubbed her temples. "Just say 'arr' a lot and point at things. Children are extremely stupid, it's their best quality." "And the mother? Denise? She hosted the bake sale. She has *instincts*, Molly. She caught a raccoon in her chimney with a laundry basket and a broom." "Denise will be occupied. At fourteen-oh-six, an anonymous caller informs Denise that a car matching her Volvo has been struck in the grocery lot." "That's cruel." "That's *tactics*." Bill was quiet for a moment. "What if there are gift receipts?" "Then we return the presents for store credit, which is the beautiful part, and the pirate gets forty percent." "Fifty." "Forty-five, and you keep the hat." Bill extended a hand across the ruined napkin, over the house with the terrible face, and shook. "Arr," he said, in flawless Australian.
