Molly crouched behind the hedge, studying the balloon-strangled cottage while Bill balanced a clipboard on one knee. Inside, children shrieked with the wild authority of pirates already paid in cake. A banner read HAPPY BIRTHDAY, LUCY in letters. “Remember,” Molly whispered, “we are not monsters. We take only wrapped items, no pets, no homemade cards, and absolutely no unicorn piñata.” Bill nodded solemnly. “Agreed. Also, if anyone asks, we are entertainers.” “You brought disguises?” “I brought two mustaches and a kazoo.” “That is one disguise and one confession.” “It worked at the mayor’s brunch.” “You were arrested at the mayor’s brunch.” “Briefly admired by security.” Molly sighed. The plan, as drawn by Bill, was a crayon map featuring a dragon where the back door should be. The presents glittered beneath the window, an Everest of bows and suspiciously educational rectangles. “Phase one,” Bill said, “we mingle.” “With seven-year-olds?” “I have range.” “You have frosting on your eyebrow.” “That’s my character.” A tiny girl opened the gate and stared at them. “Are you the magicians?” Molly stood, smiling. “Yes.” Bill blinked. “We are?” “New plan,” Molly said. “We make presents disappear, then reappear, publicly.” “Fine. I prefer magic to prison, honestly.”
