The van smelled of stale coffee and regret. Molly peered through binoculars at the backyard, where a sea of sugar-crazed toddlers swarmed a piñata shaped like a unicorn. Bill sat in the driver’s seat, polishing a grappling hook with a baby wipe. “Remind me again,” Molly said, “why we’re robbing a six-year-old’s birthday party.” Bill grinned. “Because the kid’s dad is a tech mogul. The presents aren’t just toys, Moll. They’re prototypes. Limited edition. Untested.” “Untested? So the loot might explode?” “Only if you shake it.” Bill held up a tiny stuffed robot. “This little guy? Worth more than my first car. If my first car was made of gold and could do your taxes.” Molly adjusted her clown nose. “We’re going in as entertainers?” “Best cover ever. Nobody questions a clown. Or a magician. You’re Magenta the Miracle Magician. I’m, er, Chuckles the Clown.” “Chuckles?” Molly sighed. “Really?” “It’s nostalgic. Now listen. Phase one: I distract the adults with a balloon animal demonstration. Phase two: You slip into the gift room and start bagging. Phase three: We exit through the bouncy castle, cut the anchor, and float away like beautiful, criminal balloons.” “Float away? Bill, the bouncy castle is tethered to a minivan.” “Details, Moll. Details.” Bill handed her a hollow wand. “Inside is a collapsible duffel. Don’t pull the rabbit out unless it’s an emergency. The rabbit bites.” Molly pocketed the wand. “What about the birthday girl?” “She’ll be too busy crying over stolen cake. Kids cry at parties. It’s tradition.” “And the parents?” “Dad will be showing off his smart house to the other dads. Mom will be photographing the tragedy. We’ll be ghosts.” Molly checked her watch. “We have a twelve-minute window before the pizza arrives. Once thirty kids smell pepperoni, chaos is our exit strategy.” “Exactly. Remember the signal?” Bill honked the van’s horn, which squeaked like a rubber duck. “When you hear that, you grab the goods and meet me at the fence.” “That’s not a signal, Bill. That’s a toy.” “It’s memorable.” Molly raised an eyebrow. “What’s phase four?” Bill froze. “There’s no phase four.” “There’s always a phase four. Phase four is where everything goes wrong and we improvise.” Bill grinned. “Ah. That’s my favorite phase.” She reached for the handle. “Remind me to update my résumé.” “Add ‘professional balloon artist,’” Bill said. “It pays terrible, but the tips are explosive.” Molly opened the door. “If this goes sideways, I’m telling the cops you forced me.” “Please. I’m the one wearing the oversized shoes.” Bill stepped onto the sidewalk, then turned, suddenly serious. “Molly?” “Yeah?” “No matter what happens, don’t eat the cake. It’s probably vegan.” She groaned. “That’s the real crime.” Bill adjusted his wig. “Then let’s go commit a felony.” Molly sighed. “Try not to get frosting on the loot this time.” “No promises.” Bill pushed open the gate. “After you, Magenta.” They walked toward the party, one clown, one magician, and one terrible idea.
