Molly crouched behind the hedge, peering at the church hall where balloons bobbed like smug jellyfish. Bill unfolded a napkin map covered in cake crumbs. "Front door has mums, back door has dads, window has a clown," Molly whispered. "Clowns are weak at the knees," Bill said. "I brought custard." "That's dessert, not equipment." "It's both if thrown confidently." Inside, children shrieked the ancient birthday chant. A mountain of wrapped boxes glittered beneath a banner reading HAPPY SIXTH, TABITHA! Molly adjusted her black turtleneck, which had a sticker on it saying HELLO, I'M SNEAKY. "Phase one: distract magician," she said. "Phase two: snatch presents. Phase three: ethical wobble and return anything handmade." Bill frowned. "What about batteries included?" "Gray area." A pony trotted past wearing a tiara and the expression of a retired judge. Bill saluted it nervously. "If the pony talks, we abandon the job," he said. "If the pony talks, we hire it as lookout." "No named plush rabbits." "Agreed. They have lawyers and tragic eyes." "Also avoid glitter." "Always avoid glitter." "And raisins." Bill patted his sack. Then the hall doors opened. Tabitha marched out, crown askew, holding two cupcakes. They froze solid.
