Are all the episodes based on books?
Since they cancelled the show I decided I had to read all the books

... well, let's be honest; I'd have read them anyway. It would just have taken me more time to get around to it. There are quite a few episodes I haven't seen because I

didn't like the show at first. I thought Lynley was stuck up and arrogant. I guess that makes me remotely similar to Havers

And by the time I warmed up to him, there were only aboout 4 eps left...
I'm currently reading "Playing for the ashes", which I haven't seen yet. The DVD arrived two days after I started the book, but so far I've managed to resist the temptation

I've just watched "For the sake of Elena" three times instead
