Thanks are due to our brilliant friends who’ve answered many hypothetical and occasionally off-the-wall questions with patience and imagination. These include: Rupert Symons, Mark Kalderon, Philip Lelliott, Marie Laure Legroux, Dolores Smith, Julie Weiner, Elaine Townshend, Lord Tombs of Brailes, Peter Byrom, Janine Watson, Marie Gerrard, and Wynford Dore. And thanks to those experts too numerous to mention who fielded our weird phone calls and even weirder enquiries: the nice man at the Trading Standards office, the beekeeper, the desk sergeant at Stratford Police Station, the person at the accreditation office, and many others.
