It takes me a while to get into these but when I do I find them difficult to put down. Working my way through the Instinct series books I have managed to pick up for free.

Started reading this directly after Killer Instinct, November 22nd, 2012 (late in the night).
OK, but more 3.5 than 4. A few questions where not asked, which I found obvious, they could have proven the identity of real killer sooner.
While the book would have been shorter (10% I guess), it would not leave me with the feeling that they have not done all they could.
And near the end the explanation for uncovering the evidence about the identity feels rushed.
Could have been better.
What I really like that the author has no qualms about killing sympathetic persons, although in this book it is not a main role.
In time I will read more of this series, but for now I will try another new author.
