Molly spread the hand-drawn blueprint across the hood of their dented getaway van, which still had a faded Clowns-4-Hire logo peeling off the side. The paper showed a bouncy castle, a folding table labeled CAKE, and a terrifying red circle around a pile of brightly wrapped boxes. She tapped the circle with a dramatic flourish. "This is Fort Knox for six-year-olds, Bill. We go in through the bouncy castle." Bill adjusted his oversized clown nose, which squeaked indignantly. He had not signed up for children's entertainment when he became a professional thief, and the elastic was chafing his dignity. He stared at the diagram as if it might bite him. "Molly, last time you said easy score we ended up in a petting zoo jail." Molly grinned. She loved that story. The goats had been terrible negotiators but excellent escape artists. She pulled out two tiny party hats and jammed one onto Bill's head with the reverence of knighting a very reluctant soldier. "Relax. The mom posted the schedule online. Pinata at three, presents at three fifteen. That's our window." Bill squinted at the tiny print that said ENTERTAINMENT: MAGIC CLOWN - 2:30 PM. A cold sweat formed under his makeup. He pointed a trembling finger at it. "That's us. We are the magic clown. I don't know magic, Molly." Of course there was a plan for that, Molly explained, unfolding a second sheet that simply read ABRACADABRA LOUDLY AND RUN. Bill felt his soul leave his body. The van smelled faintly of old greasepaint and poor decisions. "Trust the process. You distract with balloon animals, I grab the loot, we vanish before juice boxes." Bill attempted a balloon dog. It popped and sounded exactly like a gunshot in the quiet cul-de-sac. Somewhere, a child started crying preemptively. Molly patted his shoulder sympathetically while stealing his wallet to demonstrate technique. "Okay, but if we get caught by a mom with a clipboard, I'm blaming you forever." "Deal. And if we succeed, you get the giant teddy bear. It matches your inner child." They bumped fists. The party hats wobbled. Behind them, the van's side door slid open by itself, revealing a mountain of stolen traffic cones and one confused pigeon. It was not the most professional heist setup in criminal history, but it had heart, mostly clogged with glitter. Molly checked her watch. Two twenty-five. Showtime approached with the inevitability of a sugar crash. She handed Bill a squeaky hammer and a look of profound, unwarranted confidence. "Remind me why we need kids' presents? We could rob a bank like normal criminals." "Because banks don't have limited edition dinosaur plushies that resell for four hundred bucks, Bill. Think big." Bill considered this. It was flawed logic, but the plushie did sound soft. He hoisted the bag labeled TOTALLY NOT STOLEN GOODS and followed Molly toward the distant sound of off-key singing and parental desperation. The heist was on. "If I have to sing Baby Shark, I'm quitting crime forever." Finally.
