I started this series on book number five, thanks to a deal on the audio price, but I didn’t notice that it was part of a series so it obviously works very well as a standalone.
Frieda Klein is a complicated woman and getting into her mind-set, having not read previous books in the series, was difficult. She’s intelligent and logical but not predictable. I enjoyed following the mystery from her point of view although I had my reservations about her own motives. The author unravelled the story in a way that it was impossible to foresee what would happen and that mystery was exciting. I have now put the rest of the series on my reading list but I think this time I should start at the beginning.
