Molly studied the mansion through binoculars while Bill balanced on a hedge, wearing a stolen clown nose and the expression of a man regretting several choices. “Door?” Bill whispered. “Front gate,” Molly said. “We stroll in with the entertainers.” “The balloons?” “Diversion.” “The cake?” “Necessary sacrifice.” They had planned the operation for three days, though most of that time had been spent arguing over whether a kazoo counted as a musical instrument or a cry for help. Tonight, the children’s party blazed behind the windows, a kingdom of paper crowns, frosting, and brightly wrapped loot. Molly adjusted her feather boa. Bill lifted a plastic trumpet. Together, they marched toward the gate with the confidence of professionals and the musical ability of wounded geese. A toddler spotted them and applauded. Bill bowed, accidentally releasing a balloon animal shaped like a giraffe. It drifted skyward, carrying their getaway map. Inside, Molly located the presents beneath a banner reading HAPPY BIRTHDAY, NED. Bill began performing magic, producing scarves from his sleeves, pockets, and, alarmingly, his trousers. While the adults laughed, Molly loaded gifts into a laundry cart. Then Ned approached, clutching a cupcake. “Are you robbers?” he asked. Molly froze. Bill dropped the trumpet. “Only recreationally,” Molly said. Ned considered this. “Can you steal my boring socks?” Minutes later, the thieves fled with the socks, three rubber ducks, and a lifetime ban from children’s entertainment.
