If this is your first Sheila Quigley book, I strongly recommend that you read the previous two novels before this one. This is not her best (possibly the first, 'Run For Home' fits this bill). Unless the reader is aware of the characters, most of whom feature regularly in the previous books, this is a murder mystery which is slowed down by, as before, the 'think' bubbles attached to more and more of the characters as we move to a rather poor ending.
The author makes no effort to hide the culprits nor the likelihood of the next victim so a good part of the book is now taken up more with - in the main - the social life (and stresses) of DI Lorraine Hunt and DS Luke Daniels.
I gather in the next book, Luke's newly found daughter takes centre stage. Whereas I was greatly looking forward to Quigley's third novel after reading 'Bad Moon Rising', I cannot say that my next read will be 'Every Breath You Take' although, to be fair, I will continue with the saga for the time being.
This isn't to say readers of gritty northern life will be disappointed; it's just that her earlier stories were better.
