“Bill, tell me again why we’re crouched behind a clown car outside a seven-year-old’s birthday party,” Molly whispered. “Because,” Bill said, adjusting his black gloves, “the mark is rich in loot, the security is laughable, and the frosting budget alone suggests valuables.” Molly peered through a hedge at the backyard. “You mean presents.” “I mean presents,” Bill said. “But I prefer the romantic term.” A burst of children’s laughter floated over the fence, followed by a shriek from a helium balloon. Molly flinched. “This feels wrong.” “Of course it does,” Bill said. “That’s how you know it’s a proper heist.” She sighed. “We are stealing from children.” “Technically,” Bill said, “we are liberating gifts from an unregulated distribution system.” Molly turned to him. “Did you rehearse that?” “I wrote it on the drive over.” A woman’s voice called from inside, “Okay, kids, present time!” Bill’s eyes shone. “Now’s our window.” Molly grabbed his sleeve. “We are not doing this if there’s a bounce castle.” Bill blinked. “There’s a bounce castle?” She stared at him. “You didn’t notice the bounce castle?” He grinned. “Molly, that’s not a complication. That’s cover.”
