Molly spread the blueprints across the sticky diner table, narrowly avoiding a puddle of syrup that had been there long enough to develop its own ecosystem. Bill leaned in, squinting at the hand-drawn map like it was the Dead Sea Scrolls, if the Dead Sea Scrolls had been illustrated by a seven-year-old with a grudge against architecture. "This is the Henderson house," Molly said, tapping a lopsided rectangle. "Saturday at two. Theme is unicorns." "Unicorns." Bill rubbed his stubble. "So we're stealing from a six-year-old." "She's turning seven, Bill. Have some respect." Bill had been in the business for twenty-three years. He'd robbed casinos, art galleries, and once, memorably, a yacht belonging to a Latvian pop star. He had not, until this moment, considered the ethical implications of taking an American Girl doll from a child named Madison. "The presents pile up on the dining room table," Molly continued. "Average suburban birthday haul is eight hundred bucks, tax-free. We hit fifteen parties this summer, we clear twelve grand, easy." "And how exactly do we get in? I don't think I blend with the under-four-foot crowd." Molly grinned and slid a photograph across the table. It showed a limp, deflated costume of a purple dinosaur with one eye hanging off by a thread. The other eye conveyed decades of trauma. "Absolutely not." "Bill." "Molly, no. I have dignity." "You stole a commemorative spoon from a retirement home last month." "That spoon had historical significance!" She sipped her coffee, unmoved. "You're the entertainment. I'm the assistant. While Barney the Dinosaur distracts the kids with a sad little dance—" "I will not dance." "—I quietly load the loot into my magician's trunk and we walk out the front door to a round of applause." Bill stared at the costume photograph. The dinosaur stared back, pleading for release from whatever hell it inhabited. "What if a kid hugs me?" "Then you hug them back, Bill. You are a professional." "What if a kid cries?" "Children cry constantly. It's their primary means of communication. Ignore it." "What if the *parents* ask questions? They book these things months in advance. They'll know we're not the real Unicorn Princess Party Squad." Molly reached into her purse and produced a laminated business card, complete with a glittery logo and a phone number that rang through to a burner in her glove compartment. She had a voicemail greeting recorded in what she called her "suburban mom" voice. It was unsettlingly convincing. Bill exhaled slowly, the way a man does when he realizes his life has taken a turn he cannot explain to his mother. "One question." "Shoot." "Why me in the dinosaur suit? Why not you?" Molly folded the blueprints with the crisp efficiency of a woman who had already won the argument. "Because, Bill," she said, standing and dropping a crumpled five on the table, "I look terrible in purple."
