Molly crouched behind the hedge, peering through a gap in the leaves at the brightly decorated garden. Balloons bobbed from every tree, a banner announced HAPPY BIRTHDAY, MILO!, and somewhere beyond the picket fence, a dozen children shrieked with the alarming enthusiasm of small pirates. Bill adjusted his bow tie. “You’re sure this is the right house?” “It has the inflatable dragon.” “Three houses have inflatable dragons.” “This one has the dragon wearing a crown.” Bill considered the evidence. “Criminally convincing.” Their target stood beneath a striped gazebo: a mountain of wrapped presents, stacked higher than the birthday boy, who was currently attempting to climb them while wearing a paper hat. Molly unfolded a hand-drawn map. “We enter through the side gate, blend with the entertainers, locate the presents, and exit through the conservatory.” “Who are we blending in as?” “The entertainers.” “You’re dressed as a magician.” “And you’re dressed as a clown.” “I’m dressed as a man who made one terrible decision.” A shrill whistle sounded. Everyone in the garden froze. A woman in a sequined jacket marched toward the gazebo carrying a clipboard. “Party coordinator,” Molly whispered. “Hide.” Bill shoved himself behind the hedge. Molly slid beneath a table draped in a cloth printed with smiling cupcakes. Unfortunately, the table was already occupied by a terrier, three paper plates, and an elderly gentleman asleep in a folding chair. The terrier regarded Molly with professional suspicion. “Don’t bark,” she mouthed. The dog barked. Children turned. The coordinator lifted her clipboard. “Who’s under the cupcake table?” Molly emerged, smiling. “Magic inspection.” “Are you with the entertainment company?” “Absolutely.” Bill popped out of the hedge. “We’re the emergency clowns.” The coordinator stared at them. “The emergency clowns?” “Very rare,” Bill explained. “We’re called when ordinary clowns fail.” “Fail at what?” “Everything.” Before the coordinator could summon an adult, a boy in a silver cape grabbed Molly’s hand. “Can you make my sister disappear?” Molly glanced at Bill. “Certainly.” She snapped her fingers. Bill whipped a silk scarf from his sleeve and threw it over the nearest child, who squealed with delight. Molly pulled it away, revealing the same child still present, now holding Bill’s wallet. “Wonderful,” she said through her teeth. The children erupted into applause. Within minutes, Molly and Bill were trapped in a whirlwind of tricks. They produced rabbits, scarves, rubber chickens, and, somehow, a fully inflated canoe. Every attempt to approach the presents was interrupted by another demand. “Make Dad disappear!” “Make the dog talk!” “Make the cake bigger!” Bill leaned toward Molly while balancing six plastic cups on his head. “The presents are guarded by children.” “Then we use the oldest trick in the book.” “What, misdirection?” “No. Cake.” When the birthday cake emerged, Molly pointed dramatically toward the sky. “Look! A flying unicorn!” Every child turned. Bill seized the moment, scooping the presents into a wheeled toy wagon. He made it three feet before the terrier leaped into the wagon and the birthday boy climbed aboard. “Destination?” Bill panted. Molly sprinted beside him. “The conservatory!” They burst through the glass doors, towing their noisy cargo. Inside, Bill tripped over a potted fern, the wagon tipped, and presents scattered across the floor. The children cheered. The coordinator sighed. “You two are the best entertainers we’ve ever hired.” Molly brushed wrapping paper from her sleeve. “We accept cash.” Bill glanced at the mountain of gifts. “And perhaps one of those board games.” “Only if it’s not Monopoly.” The terrier barked again, apparently demanding royalties.
