At midnight, Molly and Bill crouched behind the hedge of Mrs. Puddle's fortress, studying the children's party. Paper dragons dangled from the porch, a kazoo orchestra shrieked indoors, and one parent guarded the gift table. Molly unfolded blueprint. Bill held the flashlight, making himself look like a haunted accountant. Equipment included two inflatable costumes, a grappling hook, three rubber chickens, and a sack labeled EMERGENCY BALLOONS though it contained socks. Molly whispered, “Bill, the presents are stacked beside the clown. We enter disguised as balloons.” Bill answered, “Grab everything, and escape through the cake.” Bill squinted at the map. The front door was blocked by toddlers wearing cardboard crowns. The side gate squeaked like an outraged mouse. Their route led across the lawn, past a sprinkler, beneath a banner reading HAPPY BIRTHDAY, TIMMY, and into the punch bowl. Molly inflated her costume. It expanded into a purple sphere with feet. Bill's became a yellow sphere with a mustache. They rolled downhill, collided with a garden gnome, and ricocheted through the window. Children cheered. The thieves bounced toward the presents, stealing everything. A dozen children applauded, mistaking the operation for a new game called Rob the Robbers, which seemed uncomfortably accurate.
