Molly adjusted her fake mustache and peered through the hedge at the birthday party. A bouncy castle wobbled in the yard, and toddlers ricocheted inside it like caffeinated pinballs. Beside her, Bill crouched in a full-body dinosaur costume, his tail sweeping a neat arc through the mulch. "Presents are on the table by the balloon arch," she whispered. "Forty minutes until cake." "I still think the disguise is brilliant," Bill said. "You look like a dinosaur, Bill." "Exactly. Nobody questions a dinosaur at a children's party." "You refused the clown outfit." "Clowns are terrifying. I have standards." Molly unfolded a hand-drawn map, smoothing it over her knee while a parent wandered past holding a juice pouch. Both thieves froze until the man wandered off, humming. "I'll distract the adults as the magician's assistant," she said. "You stuff the gifts into the tail." "The tail isn't spacious." "Then be selective. Anything bicycle-shaped." Bill nodded gravely. "And if a child catches me?" "Roar." "Roar how?" "Like you mean it." Bill attempted a small, wounded roar. A nearby squirrel abandoned its acorn and fled. Molly closed her eyes. "We'll work on it."
