I like your wife!
The preview option does allow people to decide, doesn't it? I was brought up in a very religious household. My father was a preacher, so absolutely no swearing. But that is not like the modern world. Swearing is a stress marker in speech, and it is very general, and always has been. There's swearing in Chaucer and Shakespeare, but the words are different. It was a constant moan amongst writers on The Bill that the language was not realistic - or the instruction that tired coppers should never "accidentally" hit some toe-rag's head on a car door. The language in EastEnders is very unrealistic. But those are prime time TV - a novel is not.
Two characters in the novel swear. Plenty of others don't. I think that's pretty true to life, really. I've tried to have Johnny describe the village as it is. I hope you will see through the odd casual F word to the affection I have for the place and its people.
I started writing book two last night. If - as my father would have said - the Good Lord spares me, bearing in mind that I'm 80 in September, it will be out in the summer.
