Cutting edge - Allison Brennan

When a top engineering executive is murdered and his office torched, the firm's security expert Duke Rogan is determined to get the bottom of the assault himself. He pulls every string he has to be assigned as a civilian consultant to the FBI's joint task force, headed up by Nora English, who at first believes the attack to be a simple case of domestic terrorism.

But the autopsy is strange: the man died from multiple knife wounds - not stab wounds - and slowly bled to death with no bones or organs punctured. And when another body is found with the same MO, this one a high-ranking government official, Nora begins to believe something far more evil is at work. Especially as her number one suspect has already been taken out of the equation . . .
