Molly lay flat on the hedge-top, binoculars trained on the bouncy castle across the lawn. Bill wheezed beside her, wearing a balloon-animal hat he insisted was tactical camouflage. Below, forty children shrieked around a table buried in gift-wrapped treasure. Somewhere in that pile sat a remote-controlled monster truck, three scooters, and a mysterious box the size of a refrigerator. Molly had been planning this job for six weeks, which was five weeks longer than the birthday girl had been planning her own. A clown drifted past, juggling with sinister confidence. Bill shuddered. He had never recovered from the incident at the county fair, and he refused to discuss it. "Clown at two o'clock," he whispered. "I'm not doing this." Molly lowered the binoculars and gave him the look she reserved for amateurs and people who chewed loudly. Then she pulled two foam pool noodles from her duffel bag, handed him one, and pointed at the castle, where the children were beginning a game of pin the tail on the donkey. "Blindfolds, Bill," she said. "Nobody sees anything." Bill considered this, adjusted his hat, and slowly nodded. "Fine, but I'm keeping the hat," he said. Somewhere, a piƱata began to weep.
