Molly Finch studied the invitation pinned to the laundromat corkboard as if it were a treasure map drawn in crayon. Bill Bixby held a paper crown to his head and frowned at the elastic, which had already defeated him twice. The party was for little Archibald Pease, age six, and the gifts were rumored to include robots, rockets, and one suspiciously large box humming with possibility. “We are not monsters, Bill, just temporarily gift-oriented.” Bill lowered the crown. “Bring ribbon.” Their headquarters was the folding table beside Dryer Three, where Molly arranged jelly beans into a floor plan and Bill ate the emergency exits. Every few minutes a dryer coughed up socks, startling them into heroic poses. “The clown worries me.” “Everything worries you.” “Especially clowns, Molly.” Molly tapped the biggest jelly bean, red and smug. The presents, she explained, would be guarded by grandmothers, toddlers, and a dog wearing a bow tie. Bill considered this and wrote beware dog? on his palm. Molly crossed it out and wrote befriend dog. By dusk, their scheme gleamed: arrive smiling, leave celebrated, and maybe return everything after cake, depending on flavors. Outside, rain applauded their wickedness with tiny, uncertain, perfectly timed fingers.
