Molly crouched behind the hedge like a burglarious flamingo, one boot sunk in a flowerpot, studying the bungalow blazing with pastel balloons. Inside, shrieks of birthday joy rose and fell like a fire alarm played on kazoo. Bill unfolded a hand-drawn map of the garden, the paper greasy from sausage rolls and bad decisions. He had labeled the trampoline "north wall" and the clown "probable guard dog." "Front gate, cake table, presents. In, out, vanish," Molly whispered. Bill adjusted his paper crown disguise. "What about the magician?" "Smile, clap, pinch his wand, and keep moving." They watched a pirate in face paint herd children toward musical statues, leaving the loot stacked beside a cardboard castle. Bright bags glittered there, stuffed with plastic dinosaurs, glitter pens, and enough batteries to power a small coup. Bill's eyes shone with professional admiration. The plan was absurd, which meant it suited them perfectly. Molly would pose as an exhausted aunt. Bill, carrying a tray of lemonade nobody had ordered, would drift straight to the presents. By the time the candles were lit, the mountain would be gone, and the children would blame the magician. Somewhere, a balloon popped like a starting pistol that afternoon.
