The back room of Bill's Pawn & Loan smelled like mothballs and bad decisions. Molly sat backward on a folding chair, chewing gum like it owed her money, while Bill spread a hand-drawn map across a card table. "So it's a bounce house," Bill said, tapping the paper. "Right here. Inflatable castle. That's our way in." "You want us to crawl through a bounce house." "I want us to crawl through a bounce house." "Bill, we are forty-one and thirty-eight years old respectively." "I'm thirty-nine." "You are not thirty-nine." "I am thirty-nine in my heart." Molly spit her gum into a napkin and leaned forward. "Walk me through this. We're stealing birthday presents. From a six-year-old." "Timmy Hargrove. Turning seven. And it's not just Timmy's presents, it's *everybody's* presents, because apparently rich people bring gifts like they're compensating for something. My source says there's a PlayStation in there. Multiple PlayStations, Molly. Redundant PlayStations." "Your source is a birthday clown." "Reggie sees things. Reggie knows things." "Reggie once told you the mayor was a lizard person." "And I have never seen conclusive evidence to the contrary." Molly rubbed her temples like she was trying to start a fire with friction alone. "Fine. Say we get past thirty screaming children. Say we get past the bounce house, the clown, and whatever parent is currently live-tweeting the piñata situation. How do we get the presents *out*?" Bill grinned and produced, with the flourish of a man revealing a Fabergé egg, a costume on a hanger. "...Bill. That's a dinosaur costume." "That's a *T. rex* costume." "Why." "Because nobody questions a dinosaur at a birthday party, Molly. Dinosaurs have diplomatic immunity at these events. I walk in, I do a little roar, kids love me, I'm suddenly part of the *entertainment budget.* Then I just — " he mimed scooping motions with his stubby dinosaur arms — "collect." "With those arms? You can't pick up a Capri Sun with those arms." "I've made accommodations." He unzipped a hidden panel near the belly, revealing a duffel bag folded inside like a marsupial pouch. "Kangaroo-rex." "That's not a real animal." "It's about to be very real for Timmy Hargrove." Molly stared at the costume, then at Bill, then back at the costume. "This is genuinely the worst plan you've had since the ice cream truck heist." "That plan *worked.*" "You gave forty children lactose poisoning and got chased by a woman named Denise for six blocks." "Denise was fast for a woman in heels, I'll give her that." Molly sighed the sigh of a woman who had made poor life choices and intended to make several more. "Fine. I'm the party planner. You're the dinosaur. But if one kid cries—" "They won't cry." "If one kid cries, Bill, we abort, and you're buying me a real dinner, not gas station sushi." "Deal. Now help me find the tail. I think I sat on the tail."
