The van idled behind a bouncy castle warehouse, headlights off and engine ticking like a nervous clock. Molly spread a blueprint across the hood, a crayon-scribbled map of Tommy Pickett's seventh birthday party. Bill squinted through binoculars shaped like a dinosaur. "Vents?" Bill asked. "Vents," Molly said. "Forty feet of ductwork, right above the cake table." Bill nodded gravely and adjusted his ski mask, which bore a cartoon unicorn. He had insisted on it. Nobody suspects a unicorn, he had argued, and Molly had lost the argument by lunchtime. Through the warehouse windows, forty children shrieked in unison while a clown with a squeaky voice led a conga line past the gift table. Mountains of glittering boxes towered beside a plastic princess castle. "Every one of them is going in our bag," Molly said. "Even the ones shaped like socks." Bill pulled a rope from his jacket and tied it to the roof rack with a knot he'd learned from a sailing video. It came loose immediately. He tied it again, muttering under his breath. "Ready?" Molly asked. "Born ready," Bill said, then tripped over a tricycle and scattered the blueprints across the pavement.
