Why are so many of your despicable characters named “Platt?”

There’s a person named Charles Platt who’s lived in the US for many years but who has all the attributes that go into the term ‘Chinless Wonder’ for the British upper classes. (His uncle was in the House of Lords.) He produced a supercilious review of Hammer’s Slammers suggesting that if I’d really seen war I wouldn’t write such queasy voyeurism. I didn’t respond directly–you don’t respond to reviewers, in my judgment–but I haven’t forgotten that either.
