Molly spread the hand-drawn map across the hood of their dented minivan. It was covered in crayon, which she had stolen from a toddler at a restaurant earlier that morning. She tapped a wobbly circle near the center. "The presents will be stacked here, next to the bounce house," she said. "We'll have a forty-five second window between musical chairs and cake." Bill squinted at the map, turning it sideways. His balaclava was already on, though the party didn't start for three hours. "What about the clown?" he asked. "The clown is a non-issue. He's got a balloon animal queue until two-thirty. He'll be too busy making dachshunds to notice us." Bill chewed his lip. The afternoon sun beat down on the parking lot of the strip mall where they'd been conducting surveillance on the bounce house rental company for weeks. "And the parents?" "Distracted. I've arranged for a very aggressive essential oils salesperson to arrive at exactly two-fifteen." "That's diabolical," Bill whispered, genuine admiration softening his voice. "Thank you. Now put on your party hat. We're going in as grown adult guests, which means we need to look festive and completely unsuspicious." "Nobody will suspect a thing," Bill said, adjusting his balaclava beneath a glittery cone hat.
