Rain stitched silver lines across the windows of the closed bakery where Molly and Bill crouched beneath the awning. Across the street, the community hall blazed with paper stars and birthday noise. Through its wide windows, a mountain of presents occupied the stage. Bill peered through binoculars. They were upside down. “That’s the haul,” he whispered. “Every last box.” Molly took the binoculars, turned them around, and handed them back. “Our plan is simple. We enter, collect the presents, and leave before anyone notices.” “Excellent. How do we enter?” “I was hoping you’d have thought of that.” “I thought you were handling the simple part.” Inside the hall, children shrieked around a cake shaped like a dragon. A grown-up in a paper crown attempted to lead them in a song, losing control somewhere between “Happy” and “birthday.” Bill watched, troubled. “Those children are very loud,” he said. “They’re children. Loud is their natural habitat.” “What if they see us?” “Then we’ll look like adults.” Bill considered this. “That’s a risky disguise.” Molly unrolled their hand-drawn map on the pavement. It showed the hall as a rectangle, the presents as a pile of stars, and a large question mark where the entrance should be. A gust of wind snatched it away. They watched it sail into a puddle. “Your map is gone,” Bill said. “It was mostly decorative.” A side door opened. A woman carrying a tray of cupcakes leaned out and spotted them. “You two!” she called. “The entertainers are here!” Molly straightened. Bill straightened too, then tried to look entertaining. His expression suggested a man remembering a tax audit. “We’re not—” Molly began. “Wonderful,” the woman said, thrusting a pair of floppy hats at them. “The children have been waiting for the clowns.” Bill whispered, “We’re clowns now?” “Only if you do it badly.” They were swept inside before either could object. The children greeted them with the reverence usually reserved for visiting royalty or unusually large dogs. Molly found herself holding a balloon sword. Bill was given a red nose and a plate of cupcakes. “Do clowns steal presents?” he murmured. “Not in front of witnesses.” A small girl tugged Molly’s sleeve. “Can you make my brother disappear?” Molly glanced at the boy, who was already disappearing beneath a pile of streamers. “I can make your present disappear,” Bill offered, reaching toward the gift table. Molly slapped his hand away. “Magic trick?” the girl asked. “Absolutely,” said Molly. “Bill will make one cupcake vanish.” Bill looked at the tray. “That’s not a trick. That’s lunch.” The children roared. The birthday boy laughed so hard that frosting landed on his crown. Molly caught Bill’s eye. For one bright moment, they were the most popular people in the room, and not a single present was in their possession. Then a child placed a wrapped box in Molly’s arms. “This one’s for my grandma. Can you keep it safe?” Molly looked at Bill. He looked at the box, then at the children, who were watching him with hopeful faces. “Right,” he said, tucking it carefully beneath the table. “We’re guarding the loot.” “Good,” Molly said. “That’s almost the opposite of stealing.” “Still counts as a job.”
