Which book is the right one? Dead girls do not lie?

My question is which of the dead girls do not lie is the right books?

There's the novel that has such a red cover and then the other from the Netflix series as a cover, and since I've seen the series and I feel connected with the content of the Netflix series I really want to buy the book but I do not know which one of it, can one help me?

Kind regards

I have the red and that is exat as described in the film, of course, also more detailed. So I would recommend to you from my side just the red, because unfortunately I do not know how the other is.

The red is the book. After the series was shot. I would recommend that.

The second is apparently the book about the movie. Not so good.

It is in the book the same in it only on the other book the cover of the series is so people who know the series attentive that there's a book from which the series has arisen.

Otherwise, if you run past the book you may see that the title is the same, but it does not connect to it, but if you see the series cover, stick to it and maybe buy the book to find out more.
