READ ALL 5
Like Valentine and Carrie individually and how they relate to each other as partners.
These two need a little bit of love life. Maybe Carrie's firefighter date will pan out.
I realize Valentine's wife was the love of his life and had a violent death but he is ready to kiss him frogs and maybe even meet the second love of his life.
Oh yeah, the actual stories are good too!

Was pretty good. Definitely recommend reading the others first though since it felt like I was missing a bit about the characters so some things fell flat. This was the first in the series that I read.
Couple of grammer/spelling errors in the Kindle version but not too crazy to draw away from the story.
I liked the twists :)

Gripping
This book about Jack Valentine is very good. How and Casey work the case with many twists and turns makes this mystery even more engaging. If a reader enjoys a great drama, he or she will be greatly rewarded. Awesome job, Mr. O' Mahoney.

I can never give 5 stars because the law don't work the same for poor people that can't afford high price lawyer even though Jack is a p.i.poor peoples can't afford them either

I liked the Jack Valentine character and his partner Casey.
The story kept my attention and was not predictable as have been the investigator/lawyer books I have read recently.

B rated
B rated novel - decent plot but very simple read. It would not agree that it is a "gripping mystery". Written on a seventh grade level but sometimes easy reading is good.

fantastic thriller
Great book, with more twists and turns, you can never tell what will happen. Can’t wait to read another O’Mahoney book

Action start to finish
Jack Valentine weaves his way through another case, just as one weaves their way through Chicago traffic- Never in a straight line.

A fan
I am a Peter O'Mahoney fan. I like this Jack Valentine character because he isn't a private investigator that always gets it right.

WOW!
What a frightening novel. How many people do you need to search for one girl? Wko is telling the truth as to why they need to find her.
