Molly crouched behind the hedge, peering through the gap in the fence at the glowing windows of the Henderson house. Balloons bobbed against the porch. Somewhere inside, a hundred tiny voices shrieked with joy. "Right," she whispered. "Talk me through it, Bill. Slowly. I don't want any surprises." Bill squatted beside her, clutching a clipboard he'd stolen from a dentist's office. "Okay. Phase one. We slip in through the side door while the clown is doing the balloon animals." "Which clown?" "The one with the terrifying smile. Dave said he's been working the party since two." Molly squinted. "There's a clown on the lawn, Bill. He's waving at us." "Wave back. Be polite. Phase two, we find the present room." "And how do we know where the presents are?" Bill flipped a page on the clipboard. "There's a sign. It says Presents This Way, with an arrow." "You're joking." "Some parents are just trusting people, Molly. It's a beautiful thing." She sighed and pulled a pair of novelty mustaches from her coat pocket. "Fine. We need disguises. Put this on." "I am not wearing a mustache to steal a unicorn-themed dollhouse." "Nobody's asking you to like it. Just look like a dad who's been dragged here by his wife." Bill slapped the mustache on, then sniffed. "Oh no. Is that cake?" "Focus, Bill." "I'm focusing. I'm focusing on the cake. Can we at least grab a slice on the way out?" "We're not stopping for cake. We're in and out in six minutes." "You said that about the bank in Leeds." "That was different. The vault door was stubborn." "It was a revolving door, Molly. You pushed it the wrong way for twenty minutes." Molly ignored him and checked her watch. "Okay. Piñata at seven, dimming lights at seven-oh-five. That's our window. When the kids swarm the piñata, nobody notices two extra grown-ups slipping past with a sack." "What's in the sack?" "Your extra mustache, a roll of tape, and a very large bag." "Why a very large bag?" "Because I counted eleven scooters on the porch, Bill. Eleven. Those are not going to carry themselves." Bill nodded slowly, impressed despite himself. "You know, this is the most ambitious thing we've ever done." "Don't jinx it." From inside came a roar of excitement, followed by the crack of a stick hitting a piñata and a chorus of shrieks. "That's our cue," Molly said, standing up and brushing off her knees. "Remember, we're just two harmless guests who lost track of time." Bill adjusted his mustache. "Harmless. Yes. Very harmless." They strode toward the side door, two suspiciously tall party guests with a stolen clipboard and a bag big enough to hide a pony.
