I couldn't find an English translation of this book, though I think Petra Hammesfahr is one of the best German thriller authors I've read.
This was the first book by Petra Hammesfahr I knew about. I got it at a book sale because the blurb sounded interesting. A woman has been murdered/abducted every two years on the 14th of September for the last fourteen years. One exception though, September 14th 1990, the day Karen Stichler killed a cyclist in a car accident.
It turned out it was actually a good book. It was very nice to read. The story brings forward two possible suspects and during the book I just kept changing my opinion on who was the killer here. Very cleverly done. I've since read a number of her books (all the books I could find in Dutch translation) and she's become one of my favourite authors.
Note: I read a Dutch translation of this book
