The rain drummed on the roof of the getaway van as Molly pressed binoculars to her eyes. Across the street, the Hendersons' backyard glowed with balloons and a bouncy castle shaped like a dragon. Forty-three children shrieked at a pitch only dogs could hear, which suggested cake had been involved. Bill slid into the passenger seat, clutching a sack of tools and a suspiciously large bunny costume. "Presents on the porch," Molly whispered. "Only guard is a clown." Bill unfolded a napkin covered in arrows, one of which pointed directly at a cat. He nodded gravely, as though the cat were a serious obstacle. "Costume," Molly said. "Now." Bill sighed, zipped himself into the fluffy suit, and immediately sneezed three times. Feathers, or possibly ears, exploded across the seat. "Nobody suspects a rabbit of stealing a trampoline." Outside, the clown kept juggling the same three pins, looking more heartbroken with every drop of rain. Molly grabbed the sack, cracked her knuckles, and opened the door into the drizzle. "Perfect," she said. "Subtle as a fire alarm."
