Molly crouched behind the hydrangeas, studying the backyard where balloons bobbed like smug little moons. Bill held a clipboard upside down, because it made him feel official. "Right," Molly whispered, "we mingle, compliment the cake, and liberate the presents." "Children bite," Bill said. "I've seen it." "Only if you smell of fear." "I smell of ham. Is that worse?" A shriek rose from the party. Six pirates chased a fairy with a foam sword. Molly winced. "Plan adjustment," she said. "We enter as entertainers." "You can't juggle." "I can drop three oranges with confidence." Bill peered over the hedge. "There's a magician already." "Then we are assistant magicians." "Assistants don't usually arrive carrying an empty sack labeled Loot." "It's French," Molly said. "Pronounced Loo-ay." The birthday boy spotted them. "Mum! There are burglars in the bushes!" Molly stood, smiling magnificently. "Surprise! Interactive morality play!" Bill waved weakly. "Don't steal, children." The parents applauded, assuming this had been booked by someone else. The children booed until Molly surrendered the sack for pass-the-parcel. Bill sighed. "We lost the bag." Molly watched a toddler unwrap her crowbar-shaped sandwich. "Nonsense. We gained reviews and possibly a lifetime ban from the bouncy castle circuit too."
