Wowsers. Book 15 of this most excellent series and boy has the author hit it right out of the park this time! But oooof, it's very dark. If you have read this author before (and you have cos, you know, series rules and all that), you'll know that she never pulls the punches and does think up some nasty crimes. But this book really does step it up a big notch when DI Sally Parker receives an anonymous letter which refers to historic events that occurred some fifty years ago. Something about the letter stirs her and she assembles the team to try and work out what the letter writer is alluding to. But when they do realise, oh my, what a story then unfolds...
Tacking this topic is not for the faint-hearted of authors. Not just cos of the nature of the crimes and the people it affects, but also there's the ability to write with sympathy, empathy, and not sensationalise, nor downplay the details or effects. This book is written with all the right things and none of the wrong ones. Even with the darkest of subject matters, the non-pulled punches, at no time during the book did I ever feel unsafe or too overwhelmed. Even the banter which is the usual thing the author relies on to balance the tone was done in a different, more respectful way, if you get what I mean. It's hard to describe.
Outside of all that, all the rest of what you'd expect from a book by this author is front and centre. Pacing matches the narrative and the book gets on with itself very well indeed. Main characters continue to develop through the book, and new characters are just as well crafted. And, a light in the darkness that is the story, we also catch up with an old friend. Actually more than one as she also brings a few more with her ;)
All in all, a hard read, but an important and tricky topic to cover, and the author has definitely done it justice in more ways than one.
