The van smelled of stale popcorn and sour milk, which Molly decided was the perfect cover. She tapped the blueprints spread across the dashboard while Bill squinted through a pair of binoculars at the bouncy castle in the backyard of 14 Maple Lane. "Eleven kids, one clown, and a mountain of presents in the dining room," Molly said. "The clown is the problem." "The clown is always the problem," Bill said, lowering the binoculars. "Why is there a clown? Clowns are a crime against nature." "Focus, Bill. We go in through the side gate while the magician is doing the balloon trick. Nobody watches the magician. Everyone's terrified of him." Bill nodded slowly and pulled a rumpled paper bag from under his seat. "I brought the disguises." Molly opened it and stared. Two party hats, a plastic unicorn horn, and a lime green cardigan with a tag still attached. "Bill, these are not disguises. These are a hostage situation waiting to happen." "The horn is for you. It's very convincing." "I am not wearing the horn." They crept across the lawn at a quarter past three, bent low behind a hedge that smelled faintly of barbecue. Somewhere inside, a child shrieked with joy, and Bill flinched so hard he knocked over a garden gnome. It wobbled, wobbled again, then settled with a dignified tilt. "Did you just apologize to that gnome?" Molly whispered. "It looked hurt." They reached the side window and peered in. The dining room glowed with colorful wrapping paper stacked higher than the table. A tower of boxes teetered beside the cake, and one of them, sealed with an enormous bow, was actually rattling. "Something's alive in there," Bill breathed. "That's the puppy gift. Don't touch it. Dogs are unpredictable and I'm not getting bitten on a Tuesday." Bill slid the window open with a grunt, and they scrambled inside one at a time. Molly landed on a pile of crinkly tissue paper while Bill got tangled in streamers. For a moment they both froze, listening. From the backyard came the magician's dramatic announcement that the rabbit had vanished. "Perfect," Molly whispered. "Grab the big ones. Leave the socks. Nobody cries over socks." "What about the one that's rattling?" Molly sighed and reached for it. "Fine. But if that puppy bites me, I'm telling everyone it was your idea."
