“You’re certain this is the house?” Molly whispered. “Absolutely,” Bill said. “The balloon arch says, ‘Happy Birthday, Trevor.’” “And our target?” “Every present under that table.” “Molly, these are children’s gifts.” “Exactly. Small boxes, weak security, excellent resale value.” “Resale value? One package is shaped like a dinosaur.” “Dinosaurs are timeless.” “The invitation says the party is for six-year-olds.” “Then the guests won’t recognize professional criminals.” “They’ll recognize us. We’re wearing black turtlenecks.” “Children think black turtlenecks are ninja uniforms.” “Children think ninjas are invisible.” “See? We’re practically ghosts.” A shriek erupted inside. “Was that a child?” “Probably joy.” “It sounded like someone discovered a clown.” “Worse. It may be entertainment.” Bill peeked through the window. “There are twenty children, three adults, and a giant magician.” “Security?” “The magician is pulling rabbits from a hat.” “Amateur.” “Why?” “He’s distracting everyone with rabbits. A professional uses cake.” “Plan?” “We enter disguised as entertainers, compliment the birthday boy, and replace the presents with decoy boxes.” “What’s inside the decoys?” “Old newspapers.” “The children will notice.” “Not if we label them ‘mystery gifts.’” The door opened. “Happy birthday!” Molly shouted. “Who are you?” asked a woman. “Magicians,” Bill said. “Do a trick!” Molly grabbed Bill’s sleeve. “Certainly. Observe as we make every present disappear.” Bill whispered, “That’s our actual plan.” “Then try not to spoil the surprise.”
