Bill adjusted his fake mustache in the mirror of a parked minivan, as if facial hair could disguise intent. Molly crouched beside him, studying the inflatable castle through binoculars. “Tonight, we take every present.” The party’s music leaked from the house like cupcake batter—sweet, sticky, and louder than their courage. Two balloon animals bobbed near the door, guarding it with squeaky neutrality. Molly slid a wafer-thin lock-pick into a pocket, then checked the timer on her wristwatch: fifteen minutes until the magician began. Bill whispered, “Shh—kids cry, not alarms.” He held a glitter sack to blend with the wrapping paper. Inside, parents laughed, and the smell of frosting made everyone brave. Molly glanced at the sidewalk, where a trail of confetti glittered like breadcrumbs from an evil fairy. “We’ll be in and out before frosting.” The back window was slightly ajar, the perfect invitation for criminals with etiquette. They climbed in through the gap, silent except for Bill’s knee complaining like an old pirate. “Gloves on, hearts off.” Molly moved first, tapping each present tag with a little adhesive scanner, collecting names, ages, and chocolate varieties. The living room became a polite crime scene: stolen gifts, no casualties so far.
