Inspector Trevor Joseph has just booked leave in expectation for the birth of his baby.
But then Bill Mulcahy books him and Peter Collins on for a job in Cardiff bay.
Tracking down those responsible for a lethal new street drug called Black Daffodil.
This is a huge operation and covers a lot of the local "scene," swanky parties, luxurious apartments, yachts all the way down to the other end of the local council estates.
The police are afraid that after claiming the lives of a group of people, including another undercover cop that when this stuff hits the streets it will cause an epidemic of death and destruction more deadly than any drug that is doing the rounds.
But with a mole in the operation the culprit could be nearer than they think...
An inventive and exciting cop thriller which I was shocked to learn was the alter ego of local historical novelist Catrin Collier.
A greet read.

Murder mystery featuring undercover cops, drug dealers and criminal masterminds. Moves along with pace but rather a lot of stereotypes so not exactly convincing.

This was a very decent, solid read that had me really engrossed pretty much from start to finish.

The characters are likeable, and the plot itself is, in my opinion, a believable one. I liked the setting, it isn't one I have come across often in my reading experience.

Looking at Goodreads this looks to be book 4 of a 6 part series which doesn't surprise me. There are elements of the book that screamed previous books to me, but at the same time the author didn't alienate me by making me feel I had to have read them to understand what was going on here. Previous knowledge may make some of the events here more impactful but I still got on well with this.

I'd certainly read the rest of the series and will be adding them to my 'to read' shelf on here!

This was a decent read about a team of undercover cops who are sent out to Wales after the discovery of a new drug called Black Daffodil. One of their guys from a previous undercover op has been flung off a balcony and is in a coma and people are either hospitalised in mental institutions or dead after taking the new drug. Things go from bad to worse as the mission unfolds. I won't give any spoilers but would recommend giving this book a read

Another good read from Katherine John, involving Trevor Joseph, this time in a drug related case. A bit gruesome in places but very believable. Katherine John makes the story so real that you feel like you are actually in the places she describes. Looking forward to the next book.

Good storyline but I didn't like the way the story moved between characters so randomly, and so un obviously. I think it could have been written better and towards the end it was almost as if the word count had been reached so the finish was too conveniently wrapped up and very quickly.

Riveting, spellbinding and can't put down novel. The surprise ending makes you wish that the novel still has a hundred more pages.

I've read the previous books in the series and found this one more difficult to really get into but, by the end, I was enjoying it. I'll be reading the next one soon!
