Molly unfolded the crayon map on the dashboard. “Bill, behold: the fortress.” “That’s a bouncy castle.” “Exactly. No adult suspects the bouncy castle.” “I suspect it. It ate my shoe at niece’s christening.” “Focus. At two o’clock, magician begins. At two-oh-five, parents applaud a rabbit. At two-oh-six, we enter as caterers.” “Caterers carrying empty sacks?” “Gluten-free gift removal sacks.” “Children know presents don’t have gluten.” “Children know too much. That’s why we wear disguises.” “I’m not wearing the clown nose.” “You begged for the clown nose.” “I begged you not to buy it. Different verb.” “Fine, you’re Mr. Sprinkle, emergency balloon inspector.” “Why would balloons need inspecting?” “Because helium is a gateway gas.” “Molly, this plan has holes.” “All brilliant plans have ventilation.” “What about the birthday boy?” “Distract him with cake.” “It’s his cake.” “Then he’ll trust it.” “And if he cries?” “We leave him the educational presents.” “That’s cruel.” “Bill, we are thieves, not monsters.” “What if the presents are socks?” “Then we’ve done public service.” He peered through binoculars. “Update: there’s a pony.” Molly smiled. “Excellent getaway vehicle.” “Ponies don’t do getaways.” “Not with that attitude.”
