Molly leaned over the sticky kitchen table, unfolding a crumpled blueprint of the Henderson house. "Right, Bill. Listen carefully. The party starts at two. Bouncy castle in the back garden, twelve screaming kids, and a clown named Mr. Fizzbutton." Bill squinted at the paper. "Why's there a clown on the plan?" "Because clowns are the biggest security risk in London, Bill. Nobody trusts them. Nobody looks at them either. That's the beauty." "Fair enough." Bill tapped the drawing of the front door. "So we go in through here?" "Through the front, dressed as the balloon delivery team. Nobody questions a balloon man." Molly pulled two pale green polo shirts from a carrier bag. "Put this on. It says BALLOON BLAST on the back." Bill held it up at arm's length. "This is a horrible shirt." "It's a brilliant shirt. Now, the presents. They'll be stacked in the lounge, under the big tinsel tree that isn't even Christmas." "Why would anyone put presents under a tree in July?" "Because rich people are weird, and they'll never notice a couple of bin bags going missing. Trust me." Bill pulled on the shirt, which squeaked against his jacket. "And what if someone asks who we are?" "You say you're here for the balloons. If they ask about balloons, you say they're in the van. If they ask about the van, you cry." "I can't cry on command, Molly." "Practise. Ten seconds, go." Bill sniffed dramatically. "Ooh, my van. My poor balloons." "Better. Now, the bouncy castle. The kids will be inside it, which means the lounge is unguarded for ten minutes at a time." "What about the grandmother? The one with the whistle?" Molly paused. "Gran Henderson. Yes. Blueprint says she sits in the armchair by the window, knitting." "So we distract her." "We don't distract her. We compliment her knitting. Nobody can resist a compliment about knitting." Bill frowned. "That's not a plan, that's a chat." "Every good heist is a chat with a plan hiding in it." She folded the blueprint and tucked it into her boot. "Ready?" Bill grabbed a black bin bag and a helium canister. "Ready. But Molly?" "Yes?" "If that clown looks at me funny, I'm not going in."
