It was ok but not great
This wasn't the greatest of the series but not the worst either. Some things where just so predictable. Like I'm sure everyone knew Olivia was going to come back at some point and hack the security system. And then it leaves out unanswered questions or details readers would like to know. I wanted to know how the rest of the employees at the museum reacted to their boss being the thief. How did Skylar react to Toby and Tessa secretly dating behind her back. And when other agents already had that Victor guy in custody, why wasn't he already read his rights and cuffed. He should have never been allowed to get a hold of or punch Olivia. Needs to be more realistic next time.

A fantastic mystery
This was a fantastic mystery that will keep you guessing from beginning to end. What seems like an easy case, especially compared to their previous ones, ends up being anything but. It's going to take both of these exceptional Agents to get through this assignment, as well as figure out who is actually behind it all. Not a story or series to be missed!
I hate that we have to wait until next year for the next release in this series, but I know that it'll be worth it.
I would definitely recommend this book, series, and outstanding author.

Almost all of the employees had access to the diamond, but don’t seem to be the thief. They also have a murder and a few other challenges occur while trying to find the thief. Nothing is ever simple but you will feel their frustration in trying to solve this one!

Another excellent read from Elle Gray
I have read just about every book that Elle Gray has written. They have all been interesting and exciting. I have enjoyed the Blake Wilder series, Olivia Knight series, and even the Pax Arrington series. I have waited impatiently for a new release from either one of her series.
She has very interesting story lines for each of her books. I don’t know how she can keep everyone straight in the various series. I can’t wait for the next book.

The Grand Heist ( Olivia Knight FBI Mystery Thriller Book 17)
OMG!!!!!!!!!! This book was amazing. Olivia and Brock get to go undercover in a museum, to find a missing diamond, but this museum is wrought with misfortune, with the curator getting into a car accident, to A co2 leak. They managed to get everyone out, but it was touch and go. They got locked into the vault and had to get out. This story just captivated me and made me want to help solve the crime. I can't wait to read the next book.

Strange that everything all happened in one place. I can't believe that so many things going on and nobody noticed nothing. Very creepy that Alasdair is back in the picture. I was shocked that Selena's health wasn't mentioned until almost the end?

I enjoyed the story but over the last couple of books following Olivia and Brock, the writing has become much more awkward, including over-use of odd adjectives and adverbs and feels like AI is being used. There has been a noticeable change in writing style over this series IMO.

Brilliant
Brilliant, as always! I enjoy not knowing the answer long before the ending. Some books, you figure out who did the deed, much too early, in Elle's books this is not typically not the case!! Her books rock!!

Not my fav
I thought it was a boring book and knew who the thief was about from the beginning. I am sure a lot of people would like it but it was not for me

who done it?
And why did someone die?
A fabulous Gupta-era gem, on loan from India, disappears from a small museum, so Olivia and Brock are sent to investigate.

Best series I've read in a long time..
Each book in this series has a very different plot that has kept my interest. I also have thought I know the answer but haven't.
