"Bouncy castle's the weak point," Bill said. "It's a children's party, Bill. There is no weak point. It's all weak point." "Then why've I been up three nights with the blueprints?" "You drew those blueprints. On a napkin. From memory." "From reconnaissance." "You stood outside a semi-detached in Croydon eating a Twix." "Deep cover." Bill tapped the napkin. "Present pile's here, by the piñata. Fourteen gift bags, one big box — bike, I reckon — and something wrapped in that paper with the dinosaurs, which is the good stuff, Molly. Nobody wraps rubbish in dinosaurs." "And the forty children?" "Distraction. That's your bit." "My bit." "You do the magic show. Balloon animals. Little bow." "I don't do balloon animals." "You did that swan at Christmas." "That was a swan-shaped grievance and you know it." Molly sighed. "What about the parents? Mums see everything. Mums have got, like, radar." "That's why we go in at cake time. Candles out, lights low, everyone singing. Thirty seconds of pure chaos." "And we walk out with a bike." "We walk out with a bike." "Bill." Molly folded the napkin carefully. "Whose birthday is it?" A pause. "...My nephew's." "Right. I'm doing the swan."
