Molly crouched behind the hedge, eyeing the rented bouncy castle as if it were a bank vault with frosting. Bill adjusted his clip-on tie, which made him look less like a criminal and more like a substitute magician. “Remember,” Molly whispered, “we smile, wave, and leave with every parcel that isn’t nailed down.” Bill peeked over the leaves. “Children notice things. Sticky, shrieking things. What’s our cover?” “We’re entertainers,” said Molly. “You juggle oranges. I make balloon badgers. Nobody trusts clowns.” “I can’t juggle.” “You can drop with confidence.” A burst of party music floated across the garden, followed by a tiny voice demanding more cake and justice. Bill sighed. “Suppose a parent asks why the magician has a pillowcase labeled LOOT?” “Then,” Molly said, “you say it’s French.” “For loot?” “For linens. Honestly, Bill, commit.” He straightened. “Fine. We charm the adults, distract the small tyrants, and abscond with the mountain of wrapped disappointment.” Molly grinned. “That’s the spirit. At last, a birthday party where we get the surprises.” “And bring larger sacks.” Bill patted his empty pockets, finding only a spoon, a yo-yo, and profound nerves. Inside, children cheered. Molly accepted the noise as reconnaissance supplied by fate.
