When Lars Hendriks arranges to meet Marit Jansen in Vienna, he is hoping their friendship will blossom into romance. What he doesn't expect is a surprise visit from his cousin Cole or the loose diamonds he brings with him.

As a CIA operative, Cole Bridger is used to uncertainty, but when his work takes him back to Vienna, he looks forward to reconnecting with Isabelle Roberts, the fellow agent he dated briefly before duty took him away from Austria. Unfortunately, his silence over the last few months has created a chasm that he can't cross without help. He barely takes a step toward repairing the damaged relationship when a brazen jewel heist seemingly links Cole, Lars, Marit, and Isabelle to the crime. The group is drawn into a deadly mystery, and once again, the treasures of Falcon Point are threatened. It doesn't take long for them to realize they have stumbled upon something far bigger and more dangerous than a simple robbery. And someone on the inside knows it.
