Molly crouched behind the community-center hedge, wearing a black turtleneck, a tiara, and the expression of someone allergic to cake. Bill unfolded a crayon map of the balloon-filled hall, upside down. "Right," Molly whispered, "we enter during the magician's finale, blend with the parents, and seize the presents before anyone suspects two adults labeled 'Definitely Not Thieves.'" "Small snag," Bill said. "That sign is on your back." "Also," Bill said, "the invitation says costumes encouraged, so my burglar mask may read as raccoon." "Excellent, Bill," Molly said. "Then look hungry, not felonious." Molly peeled off the note and frowned at glitter on her gloves. "Another snag," Bill added, "the presents are for the orphanage raffle, and the birthday boy is giving his away." "Villainy is getting emotionally complicated," Molly said. Inside, children cheered. A rabbit escaped, dragging a wand like a tiny union picket. "So we don't steal them?" Bill asked. "We steal the show," Molly said, standing. "You juggle. I apologize." Bill eyed the windows. "Can I juggle cupcakes?" "Only if you want evidence on your trousers." They marched in, surrendered a lockpick-shaped kazoo to security, and emerged an hour later with applause, frosting, and one lawful party bag each.
