Murder is only a Number (DCI Cook Thriller Series Book 3) Kindle Edition

4.1 out of 5 stars 407 ratings

Before she left she carved a number in blood on his chest. But why the number 2, if this was her first murder?

A woman stalks London. She kills at will. Her targets are men who have wronged her, or have they?

What is behind her hatred and why is she keeping count?

DCI Cook and his team know who she is, at least after she has killed the first four, but the woman disappears in plain sight. The pressure’s on to stop her, but she’s always one step ahead.

And this time, DCS Goddard can’t protect his protégé, Isaac Cook, from the wrath of the new commissioner at the Met.

  • Reviewed in the United States on July 31, 2017
    Australian author Phillip Strang has gained his platform as an adventure writer through his career installing telecommunications networks in many remote and exotic parts of the globe, including time spent in Afghanistan and Pakistan - an experience that allowed him to gain direct insights in to the ongoing conflicts there. He has also spent considerable time in Africa including Liberia, Nigeria, and Guinea. It is this direct contact with troubled countries that gives his books intense credibility: he has first hand contact with the events he shares in his books such as DCI Cook Thriller Series, of which this is Book 3 – the first two books are MURDER IS A TRICKY BUSINESS, MURDER HOUSE, MURDER WITHOUT REASON, and now MURDER IS ONLY A NUMBER.

    But it takes more than on the spot witness to bring the story Phillip has written to life in the format of a book - and that is where he towers above others creating novels with similar storylines. To bring a story of this magnitude into focus it is imperative that the foundation of the place and the people are presented accurately in order to bring the terror that is to come to meaningful life. Phillip sets his stage well form the very first page: ‘Stephanie Chalmers realised that her life was not as it should be. On the one hand, she had a husband who loved her; on the other, he was a lecherous bastard who would chase anyone half decent in a skirt. It was not as though she was beaten, or impoverished, or even neglected. Gregory Chalmers, she knew, had been a good catch when she had met him ten years previously. He had only been thirty-two then, two years older than her. Already, he had his own legal practice and was doing well. He had an easy way with words and an attractive physique with a full head of black hair. Sure, she had heard about his reputation, but she was confident she could tame him, the same way she had tamed a previous boyfriend, but that damn fool went and got himself killed in a motor accident. A tragedy as she saw it, considering all the effort she had put into the relationship. She had loved the previous boyfriend with the all-consuming passion reserved for the young and susceptible; she had no intention of repeating that mistake by falling for Gregory, her future husband, only ultimately to be disappointed. It had taken six months before he proposed to her, wed her, and then bedded her, but not necessarily in that order. She knew that he would continue to love her intensely; she knew how to do that, but she would only feel a strong affection. Still, she had reasoned, it was a good arrangement, and for nine of the ten years they had been fine.’ Scene set with only a hint of what is to come.

    The story is distilled well in Phillip’s synopsis: ‘Before she left she carved a number in blood on his chest. But why the number 2, if this was her first murder? A woman stalks London. She kills at will. Her targets are men who have wronged her, or have they? What is behind her hatred and why is she keeping count? DCI Cook and his team know who she is, at least after she has killed the first four, but the woman disappears in plain sight. The pressure’s on to stop her, but she’s always one step ahead. And this time, DCS Goddard can’t protect his protégé, Isaac Cook, from the wrath of the new commissioner at the Met.’

    Elegant writing and a keen sense of suspense – this is another Phillip Strang winner! Grady Harp, July 17

    Stephanie a love that was now lost forever , she married Gregory, a womanizer, she couldn’t tame. She had an interior design business and two children that kept her busy. A nanny was hired and then the affair, now telling Gregory that was the only reason she took the job. She was too young and trouble, and he loved his wife, and would not leave her.
    She lost control, and again when Stephanie walked in. A call to police of a child saying mommy and daddy are dead. The police know who see is. It has been men who have done her wrong. She is always head of them, and yet to be caught. Good plot that keeps one reading to figure it out.

    This is the third DCI Cook book I have read. I would leave a 3.5 if I could. I did not review the others.

    I really enjoy the books, but the endings are quick and abrupt which I really dislike. Tons of time spent on developing the characters and the murder mystery and then one to two pages on the ending. ****Spoiler Alert**** In this particular book, DCI Cook can't find the murderer fast enough so he gets replaced. Then he does catch them and gets all the praise. Why? Explain this. What happens to the murderer. Jail? Mental facility? It would have made it great to know what happened. Nope. Just her father still loved her. The end.

    I also don't enjoy DCI Cooks "love" life. He sleeps with everyone within minutes and then wonders why he is never going to settle down.

    I will continue to read the series but I really wish this author would give us a better ending.

    As with the others in this series I have read this was a great story. i have now read several in this series and have thoroughly enjoyed each of them.

    A jilted nanny snaps for no known reason, stabbing the father of the children she cares for to death. She carves a 2 on the man’s chest, and almost kills the wife when she returns early. The London police know who did it, but the woman had led a innocuous life prior to this killing. Or, had she? Who was she reallly?
  • Reviewed in the United States on March 17, 2019
    This is a genuinely difficult murderer to catch. Obviously she has mental problems but she's smart enough to elude police through all the murders she commits. The ending..... Just saying!

    5.0 out of 5 stars Murder, with a twist.
    Reviewed in the United Kingdom on October 8, 2018
    The twist being that we know who the serial killer is from early on in the book, and the story of the police being thwarted in attempts to solve the case make for a compelling and gripping read. Phillip Strang writes in a style that is both clever and entertaining. This is the third book featuring D.C.I Cook and the best yet. The characters are both believable and flawed, dealing with pressures of work and their private lives.
    If you enjoy police procedural books, then this is highly recommended for you. A page turner.

    Why does she write number 2 on her kill, who was the first. The police know her name but she seems to disappear before their eyes. How many will she kill before they stop her, if they can.
    An enjoyable read
