Molly unfolded the crayon-drawn map across the hood of their rusty van and tapped it with a gloved finger. The target was a suburban birthday party for a seven-year-old named Trevor. "The bouncy castle goes up at noon," she said. "That's our window. While the kids are distracted, we load the presents into the van." Bill squinted at the map. A smiling sun had been drawn in the corner. "Did you draw this yourself?" "I found it in Trevor's trash, obviously." He pointed to a scribbled rectangle near the house. "What's this supposed to be?" "The gift table. Sixty-three presents, minimum. I counted the RSVPs." Bill pulled his black beanie down over his ears and stared at her. "You RSVPed to a child's birthday party." "I RSVPed as Molly Henderson, regional sales manager." She rolled up the map proudly. "They said they were absolutely delighted." "We are stealing from children, Molly." "We are redistributing joy," she corrected firmly, "to ourselves." Bill looked out at the quiet suburban street, where balloons shaped like giraffes were already being tied to a mailbox. "The clown arrives at two," Molly added quietly. "We cannot be here when the clown arrives." For once, Bill completely agreed.
