Genuine, or not. Whether these were genuine enquiries is hard to tell, as this type of thing happens so often, I have gone well past the point of caring.
A joke. If they thought contacting some unknown writer, and getting his hopes up is a joke. I have news for them. It didn't work, like the many people who asked where to get my books, and never bought one. My reaction is, If it happens, it happens, talk is cheap.
