Molly spread the hand-drawn map across the van's rusty hood and stabbed her finger at a wobbly rectangle. "The presents are stacked right by the bouncy castle," she said. "We move during Pin the Tail on the Donkey. Everyone's blindfolded. It's perfect." Bill squinted carefully at the map. A glittery unicorn sticker marked one corner of the paper. "Is that a unicorn sticker?" "It marks the guard dog's location. Don't laugh." "The guard dog is represented by a unicorn sticker." "Her name is Princess. She bites." Bill rubbed his forehead slowly. Down the street, a crowd of children were singing Happy Birthday loudly and badly and enthusiastically. He could already smell the frosting from where he stood. "How many kids total?" "Ten. Eleven if you count the birthday boy." "I absolutely count the birthday boy." "Then eleven. Plus parents with cameras." Bill folded his arms and stared at the map for a long, quiet, and deeply humbling moment. "We used to rob banks," he said. "Banks don't have bouncy castles." "That was not a point in the castles' favor." Molly carefully rolled up the map and tucked it under her arm. "Gloves on," she said. "We move at cake time."
