As always Elle Gray keeps you guessing until the very end. A fast paced thriller with Blake Wilder and her team working on 2 cases at once. On is a serial killer who wants Blake's undivided attention and the other is a black market seller of anything and everything criminals could want. currently it is a dirty bomb and the clock is ticking to find the bomb and the seller before it is to late.

A Code to Kill by Elle Gray is book number 19 in the FBI Mystery Thriller series, and it did not disappoint me.
In true Blake Wilder style, she had me on the edge of my seat reading quickly to figure out how she could catch the bad guys. The ending was astonishing!

A fantastic thriller story and series!

This was a heart pounding, action packed, intriguing thriller that will hook you from beginning to end. Wilder and her team have their hands full with several cases, and are reaching a breaking point. It's certainly going to be another wild ride for this awesome group of Agents. It's definitely not a story or series that you'll want to miss!
I would definitely recommend this book, series, and outstanding author.

Can't wait for the next release and more of this fantastic series!

Great read😍

Cannot wait for the next book. Little disappointed that you put in Kit needed help considering the background you have for her experience. We should not have needed help and especially from a rookie. Her , Blake and Astra has been describe to be the best which is what so thrilling about your books. So please don't verve off. Your books are so fantastic, thrilling and full of action and suspense. Everyone should read this series if they like strong smart women, action frankly a great read,

A Code to Kill(Blake Wilder FBI Mystery Thriller Book 19)

OMG!!!!!!!!!!!! This book was amazing. Blake and her team took down "ghost", an arms dealer that the CIA didn't even believe was real and now it looks like she may have an idea, who is sending her body parts. She also took down a Bulgarian mafia king pin, someone who not only sold guns but was also into drugs, prostitution and trafficking women and young girls.

green eyes

The only thing that bothers me about your books, but don’t get me wrong. I love them. But only 2% of the world population has green eyes ,little bit more in the US but at least half or more of the people in your books have green eyes sorry Its just one of those little things that drives me crazy , but I thoroughly enjoy your books

Bang what a way to end the story.  I wasn't expecting Boyle to be such a little hard ass, I like her. 

It was was having Kit back in the game.  You sure know how to get Rick's undies in a bunch, just as Brody.  


Looking forward for more of their adventures. Spencer Song is what I'm waiting for.

Two Important Problems.

Enjoyed reading a Blake Wilder mystery again. The characters really work together to solve the problems. The problem Kit brought to Blake was an interesting subject . But there is another problem to be solved .

Amazing

Ms Gray never ceases to amaze me, once I pick up her book I usually don't put it down until I finish. Her story line doesn't drag on and I'm always surprised one way or another. Please keep Blake alive and solving crime!

This series is the very best I've ever read. This is the 1st review I've written. But it's the kind of series you can't put down. I'd be repeating myself after each book. It's taken me 2 months to read 19 books in this series. Can't put the book down.

Loved it!!

So happy that Kit is back and I love Paige. She adds a new detention to the group an I'm assuming that Lucas won't come back unless in a different capacity which I think would be great.
