"Right," said Molly, spreading the blueprint across the table. "The bouncy castle goes up at noon." "A bouncy castle," Bill repeated. "They've got a bouncy castle?" "Focus. The presents are piled near the gazebo. Northeast corner." "How many kids we talking?" "Twelve. Maybe thirteen." "Thirteen," Bill said gravely. "That's bad luck, that is." "What's bad luck is your attitude. Now, we go in through the back gate during musical chairs. Everyone's distracted." "And if someone spots us?" "We're the clowns." Bill stared at her. "We're not dressed as clowns, Molly." "We will be." "I'm not wearing a wig again. Last time I had glitter in my ears for a month." "You'll wear the wig, Bill." "The big shoes too?" "The whole ensemble." Bill slumped in his chair. "I got into this business for the glamour." "You got into this business because you failed your driving test four times and had no other options." "That's hurtful." "It's also true. Now, the cake goes out at two o'clock. That's our window. Grab the presents, load the van, and we're gone before anyone sings happy birthday." "What kind of cake?" "Irrelevant." "Is it chocolate?"
