Molly unfurled the birthday invitation across the cafe table as though it were a treasure map, except the treasure was wrapped in dinosaur paper and guarded by sugared eight year olds. Bill leaned over it, wearing sunglasses indoors, which made him look less criminal than recently concussed. The party was at Number Twelve, Happy Hippo Play Barn, Saturday at two. Molly had circled the words unlimited jelly with professional concern. "We enter as magicians, bow, collect the loot." Bill swallowed. "Children bite, Molly." Molly tapped the invitation. "Only if you smell afraid, Bill." Bill sniffed his sleeve. "I smell genius." Their plan involved a collapsible top hat, three smoke bombs bought from a garden center by mistake, and a sack labeled Laundry because Molly believed honesty confused witnesses. Bill was assigned lookout, distraction, and, if necessary, giraffe wrangling, since the Play Barn mascot was rumored to have a temper and unpaid parking tickets. Molly sketched arrows past the ball pit, around the cake table, and through the present mountain. Bill added a skull near the face painter. By dusk, the greatest present robbery in party history was planned on a napkin sticky with jam and possibly several moral consequences too.
