Thanks for your speedy response Mark. I really appreciate you going to the trouble of checking for me. That makes sense now. I must have missed the bit in chapter 10 then which is why I was confused. I will definitely go on to read some more of the series. I'm Jo(anna) Gill, but my kindle account is in my husbands name for some reason I can't remember! I hadn't realised it came up as his name on the question.?
