Scary stuff

Loved this story albeit edge of seat scary. Not giving anything away but Edwin had a collie dog, as a dog lover, what happened to the dog. A small detail that has left me worried. Sorry too that his marriage is on the brink again. Maybe the station story wil bring them back together. Highly recommended.

A definitive thriller

For those readers who enjoy thrillers of this genre don't need to look further than novels from this author. I was totally immersed in this book and have not found a better example of how a crime thriller should be put together. Brilliant twists and turns. Believable characterisation. It puts the reader there amongst the action and they won't be disappointed. Brilliant.

I always enjoy my time spent with the Lancashire police solving crimes. Once the twists and turns started in this installment they did not stop!!


I will warn that this book is darker than the previous 5 and I found myself skimming/speed reading to avoid some parts. With that said, I still look forward to the next book, but hoping it's a little lighter.

The body of a 81 year old man is found in Mertin Mere. Is there a link between this and a body found several weeks earlier in a Nature Reserve. DCI Walker and his team investigate. Then it's takes an unsuspected turn.
And entertaining and well-written modern mystery

On the whole I enjoyed the book. I did feel that the search piece went on a little too long. The characters are still worth rooting for and invested in. Living in Lancashire makes the books feel a little more real. I look forward to the next book.
