Molly pressed her back against the brick wall and unrolled a crayon drawing she'd stolen from a kindergartner's backpack. It was supposed to be the floor plan of the venue. "This is a rectangle with a dog in it," Bill whispered. "That's the bouncy castle." "That's a dog, Molly." She tapped the paper with authority. "We go in through the side entrance during the musical chairs chaos. Everyone looks left during musical chairs." Bill peered around the corner at the explosion of balloons and streamers. A clown was making an obscene amount of noise with a bicycle horn. "There are forty seven children in there," he said gravely. "Forty eight. The birthday kid counts double." "That's not a rule." "It's my rule." She zipped up her black turtleneck. "We grab the presents, we're out before cake. Nobody cries." "Somebody is absolutely going to cry." "Bill." "Multiple somebodies." Molly stuffed the crayon map into her pocket and looked him dead in the eye. "We are professionals. We have trained for this exact scenario." Bill stared back at her. "We have never trained for anything remotely like this scenario." "Semantics. Let's move."
